The Relearn theme provides configuration options to change your your site's colors, favicon and logo. This allows you to easily align your site visuals to your desired style. Most of these options are exposed thru so called color variants.
A color variant lets you customize various visual effects of your site like almost any color, used fonts, color schemes of print, syntax highligtning, Mermaid and the OpenAPI shortcode, etc. It contains of a CSS file and optional configuration options in your `hugo.toml`.
The Relearn theme ships with a wide set of different color variants. You can use them as-is, copy them over and use them as a starting point for your customizations or just create completely new variants unique to your site. The [interactive variant generator](basics/generator) may help you with this task.
Once configured in your `hugo.toml`, you can select them with the variant selector at the bottom of the menu.
## Change the Variant (Simple) {#theme-variant}
### Single Variant
Set the `themeVariant` value to the name of your theme file. That's it! Your site will be displayed in this variant only.
{{< multiconfig file=hugo >}}
[params]
themeVariant = "relearn-light"
{{< /multiconfig >}}
{{% notice note %}}
Your theme variant file must reside in your site's `static/css` directory or in the theme's `static/css` directory and the file name must start with `theme-` and end wit `.css`. In the above example, the path of your theme file must be `static/css/theme-relearn-light.css`.
If you want to make changes to a shipped color variant, create a copy in your site's `static/css` directory. Don't edit the file in the theme's directory!
{{% /notice %}}
### Multiple Variants
You can also set multiple variants. In this case, the first variant is the default chosen on first view and a variant selector will be shown in the menu footer if the array contains more than one entry.
{{< multiconfig file=hugo >}}
[params]
themeVariant = [ "relearn-light", "relearn-dark" ]
{{< /multiconfig >}}
{{% notice tip %}}
The theme provides an advanced configuration mode, combining the functionality for multiple variants with the below possibilities of adjusting to your OS settings and syntax highlightning and even more!
Although all options documented here are still working, the advanced configuration options are the recommended way to configure your color variants. [See below](#theme-variant-advanced).
{{% /notice %}}
## Adjust to OS Settings
You can also cause the site to adjust to your OS settings for light/dark mode. Just set the `themeVariant` to `auto` to become an auto mode variant. That's it.
You can use the `auto` value with the single or multiple variants option. If you are using multiple variants, you can drop `auto` at any position in the option's array, but usually it makes sense to set it in the first position and make it the default.
{{< multiconfig file=hugo >}}
[params]
themeVariant = [ "auto", "red" ]
{{< /multiconfig >}}
If you don't configure anything else, the theme will default to use `relearn-light` for light mode and `relearn-dark` for dark mode. These defaults are overwritten by the first two non-auto options of your `themeVariant` option if present.
In the above example, you would end with `red` for light mode and the default of `relearn-dark` for dark mode.
If you don't like that behavior, you can explicitly set `themeVariantAuto`. The first entry in the array is the color variant for light mode, the second for dark mode.
{{< multiconfig file=hugo >}}
[params]
themeVariantAuto = [ "learn", "neon" ]
{{< /multiconfig >}}
## Change the Favicon
If your favicon is a SVG, PNG or ICO, just drop your image in your site's `static/images/` directory and name it `favicon.svg`, `favicon.png` or `favicon.ico` respectively.
If you want to adjust your favicon according to your OS settings for light/dark mode, add the image files `static/images/favicon-light.svg` and `static/images/favicon-dark.svg` to your site's directory, respectively, corresponding to your file format. In case some of the files are missing, the theme falls back to `favicon.svg` for each missing file. All supplied favicons must be of the same file format.
If no favicon file is found, the theme will lookup the alternative filename `logo` in the same location and will repeat the search for the list of supported file types.
If you need to change this default behavior, create a new file `layouts/partials/favicon.html` in your site's directory and write something like this:
````html {title="layouts/partials/favicon.html"}
<link rel="icon" href="/images/favicon.bmp" type="image/bmp">
````
## Change the Logo
Create a new file in `layouts/partials/logo.html` of your site. Then write any HTML you want. You could use an `img` HTML tag and reference an image created under the _static_ folder, or you could paste a SVG definition!
{{% notice note %}}
The size of the logo will adapt automatically.
{{% /notice %}}
## Syntax Highlightning
If you want to switch the syntax highlighting theme together with your color variant, you need to configure your installation [according to Hugo's documentation](https://gohugo.io/content-management/syntax-highlighting/) and provide a syntax highlighting stylesheet file.
You can use a one of the shipped stylesheet files or use Hugo to generate a file for you. The file must be written to `static/css/chroma-<NAME>.css`. To use it with your color variant you have to define `--CODE-theme: <NAME>` in the color variant stylesheet file.
For an example, take a look into [`theme-relearn-light.css`](https://github.com/McShelby/hugo-theme-relearn/blob/main/static/css/theme-relearn-light.css) and [`hugo.toml`](https://github.com/McShelby/hugo-theme-relearn/blob/main/exampleSite/config/_default/hugo.toml) of the exampleSite.
## Change the Variant (Advanced) {#theme-variant-advanced}
The theme offers a new way to configure theme variants and all of the aspects above inside of a single configuration item. This comes with some features previously unsupported.
Like with the [multiple variants](#multiple-variants) option, you are defining your theme variants in an array but now _not by simple strings_ **but in a table with suboptions**.
Again, in this case, the first variant is the default chosen on first view and a variant selector will be shown in the menu footer if the array contains more than one entry.
{{< multiconfig file=hugo >}}
[params]
themeVariant = [ "relearn-light", "relearn-dark" ]
{{< /multiconfig >}}
you now write it that way:
{{< multiconfig file=hugo >}}
[params]
[[params.themeVariant]]
identifier = "relearn-light"
[[params.themeVariant]]
identifier = "relearn-dark"
{{< /multiconfig >}}
The `identifier` option is mandatory and equivalent to the string in the first example. Further options can be configured, see the table below.
### Parameter
| Name | Default | Notes |
|-----------------------|-----------------|-------------|
| identifier | _&lt;empty&gt;_ | Must correspond to the name of a color variant either in your site's or the theme's directory in the form `static/css/theme-<IDENTIFIER>.css`. |
| name | see notes | The name to be displayed in the variant selector. If not set, the identifier is used in a human readable form. |
| auto | _&lt;empty&gt;_ | If set, the variant is treated as an [auto mode variant](#adjust-to-os-settings). It has the same behavior as the `themeVariantAuto` option. The first entry in the array is the color variant for light mode, the second for dark mode. Defining auto mode variants with the advanced options has the benefit that you can now have multiple auto mode variants instead of just one with the simple options. |
### Example Configuration of This Site
{{< multiconfig file=hugo >}}
[params]
[[params.themeVariant]]
identifier = "relearn-auto"
name = "Relearn Light/Dark"
auto = []
[[params.themeVariant]]
identifier = "relearn-light"
[[params.themeVariant]]
identifier = "relearn-dark"
[[params.themeVariant]]
identifier = "zen-auto"
name = "Zen Light/Dark"
auto = [ "zen-light", "zen-dark" ]
[[params.themeVariant]]
identifier = "zen-light"
[[params.themeVariant]]
identifier = "zen-dark"
[[params.themeVariant]]
identifier = "neon"
{{< /multiconfig >}}
## Modify Shipped Variants
In case you like a shipped variant but only want to tweak some aspects, you have two choices:
1. Copy and change
You can copy the shipped variant file from the theme's `static/css` directory to the site's `static/css` directory and either store it with the same name or give it a new name. Edit the settings and save the new file. Afterwards you can use it in your `hugo.toml` by the choosen name.
2. Create and import
You can create a new variant file in the site's `static/css` directory and give it a new name. Import the shipped variant, add the settings you want to change and save the new file. Afterwards you can use it in your `hugo.toml` by the choosen name.
For example, you want to use the `relearn-light` variant but want to change the syntax highlightning schema to the one used in the `neon` variant. For that, create a new `static/css/theme-my-branding.css` in your site's directory and add the following lines:
````css {title="static/css/theme-my-branding.css"}
@import "theme-relearn-light.css";
:root {
--CODE-theme: neon; /* name of the chroma stylesheet file */
--CODE-BLOCK-color: rgba( 226, 228, 229, 1 ); /* fallback color for code text */
--CODE-BLOCK-BG-color: rgba( 40, 42, 54, 1 ); /* fallback color for code background */
}
````
Afterwards put this in your `hugo.toml` to use your new variant:
{{< multiconfig file=hugo >}}
[params]
themeVariant = "my-branding"
{{< /multiconfig >}}
In comparison to _copy and change_, this has the advantage that you profit from any adjustments to the `relearn-light` variant but keep your modifications.

On top of [Hugo's global configuration options](https://gohugo.io/overview/configuration/), the Relearn theme lets you define further options unique to the theme in your `hugo.toml`.
Note that some of these options are explained in detail in other sections of this documentation.
## All config options
The values reflect the options active in this documentation. The defaults can be taken from the [annotated example](#annotated-config-options) below.
{{< multiconfig file=hugo >}}
[params]
{{% include "config/_default/params.toml" %}}
{{< /multiconfig >}}

## Usage scenarios
The theme is usable in different scenarios, requiring the following mandatory settings in your `hugo.toml`. All settings not mentioned can be set to your liking.
### Public Webserver from Root
{{< multiconfig file=hugo >}}
baseURL = "https://example.com/"
{{< /multiconfig >}}
### Public Webserver from Subdirectory
{{< multiconfig file=hugo >}}
baseURL = "https://example.com/mysite/"
relativeURLs = false
{{< /multiconfig >}}
### Private Webserver (LAN)
The same settings as with any of the public webserver usage scenarios or
{{< multiconfig file=hugo >}}
baseURL = "/"
relativeURLs = true
{{< /multiconfig >}}
### File System
{{< multiconfig file=hugo >}}
baseURL = "/"
relativeURLs = true
{{< /multiconfig >}}
{{% notice warning %}}
Using a `baseURL` with a subdirectory and `relativeURLs=true` are mutally exclusive due to the fact, that [Hugo does not apply the `baseURL` correctly](https://github.com/gohugoio/hugo/issues/12130).
If you need both, you have to generate your site twice but with different settings into separate directories.
{{% /notice %}}
{{% notice note %}}
Sublemental pages (like `sitemap.xml`, `rss.xml`) and generated social media links inside of your pages will always be generated with absolute URLs and will not work if you set `relativeURLs=true`.
{{% /notice %}}
{{% notice info %}}
If you are using `uglyURLs=false` (Hugo's default), the theme will append an additional `index.html` to all page links to make your site be servable from the file system. If you don't care about the file system and only serve your page via a webserver you can generate the links without this:
{{< multiconfig file=hugo >}}
[params]
disableExplicitIndexURLs = true
{{< /multiconfig >}}
{{% /notice %}}
## Activate search
If not already present, add the following lines in your `hugo.toml` file.
{{< multiconfig file=hugo >}}
[outputs]
home = ["html", "rss", "search"]
{{< /multiconfig >}}
This will generate a search index file at the root of your public folder ready to be consumed by the Lunr search library. Note that the `search` outputformat was named `json` in previous releases but was implemented differently. Although `json` still works, it is now deprecated.
{{% notice note %}}
If you want to use the search feature from the file system, migrating from an older installation of the theme, make sure to change your outputformat for the homepage from the now deprecated `json` to `search` [as seen below](#activate-search).
{{% /notice %}}
### Activate dedicated search page
You can add a dedicated search page for your page by adding the `searchpage` outputformat to your home page by adding the following lines in your `hugo.toml` file. This will cause Hugo to generate a new file `http://example.com/mysite/search.html`.
{{< multiconfig file=hugo >}}
[outputs]
home = ["html", "rss", "search", "searchpage"]
{{< /multiconfig >}}
You can access this page by either clicking on the magnifier glass or by typing some search term and pressing `ENTER` inside of the menu's search box .
![Screenshot of the dedicated search page](search_page.png?&width=60pc)
{{% notice note %}}
To have Hugo create the dedicated search page successfully, you must not generate the URL `http://example.com/mysite/search.html` from your own content. This can happen if you set `uglyURLs=true` in your `hugo.toml` and defining a Markdown file `content/search.md`.
To make sure, there is no duplicate content for any given URL of your project, run `hugo --printPathWarnings`.
{{% /notice %}}
## Activate print support
You can activate print support to add the capability to print whole chapters or even the complete site. Just add the `print` output format to your home, section and page in your `hugo.toml` as seen below:
{{< multiconfig file=hugo >}}
[outputs]
home = ["html", "rss", "print", "search"]
section = ["html", "rss", "print"]
page = ["html", "rss", "print"]
{{< /multiconfig >}}
This will add a little printer icon in the top bar. It will switch the page to print preview when clicked. You can then send this page to the printer by using your browser's usual print functionality.
{{% notice note %}}
The resulting URL will not be [configured ugly](https://gohugo.io/templates/output-formats/#configure-output-formats) in terms of [Hugo's URL handling](https://gohugo.io/content-management/urls/#ugly-urls) even if you've set `uglyURLs=true` in your `hugo.toml`. This is due to the fact that for one mime type only one suffix can be configured.
Nevertheless, if you're unhappy with the resulting URLs you can manually redefine `outputFormats.print` in your own `hugo.toml` to your liking.
{{% /notice %}}
## Home Button Configuration
If the `disableLandingPageButton` option is set to `false`, a Home button will appear
on the left menu. It is an alternative for clicking on the logo. To edit the
appearance, you will have to configure the `landingPageName` for the defined languages:
{{< multiconfig file=hugo >}}
[languages]
[languages.en]
[languages.en.params]
landingPageName = "<i class='fa-fw fas fa-home'></i> Home"
[languages.pir]
[languages.pir.params]
landingPageName = "<i class='fa-fw fas fa-home'></i> Arrr! Homme"
{{< /multiconfig >}}
If this option is not configured for a specific language, they will get their default values:
{{< multiconfig >}}
landingPageName = "<i class='fa-fw fas fa-home'></i> Home"
{{< /multiconfig >}}
The home button is going to look like this:
![Default Home Button](home_button_defaults.png?width=18.75rem)
## Social Media Meta Tags
You can add social media meta tags for the [Open Graph](https://gohugo.io/templates/internal/#open-graph) protocol and [Twitter Cards](https://gohugo.io/templates/internal/#twitter-cards) to your site. These are configured as mentioned in the Hugo docs.
## Change the Menu Width
The menu width adjusts automatically for different screen sizes.
| Name | Screen Width | Menu Width |
| ---- | ------------- | ---------- |
| S | < 48rem | 14.375rem |
| M | 48rem - 60rem | 14.375rem |
| L | >= 60rem | 18.75rem |
The values for the screen width breakpoints aren't configurable.
If you want to adjust the menu width you can define the following CSS variables in your `custom-header.html`. Note that `--MENU-WIDTH-S` applies to the menu flyout width in mobile mode for small screen sizes.
````css
:root {
--MENU-WIDTH-S: 14.375rem;
--MENU-WIDTH-M: 14.375rem;
--MENU-WIDTH-L: 18.75rem;
}
````
## Change the Main Area's Max Width
By default the main area width will only grow to a certain extent if more vertical screen space is available. This is done for readability purposes as long line are usually harder to read.
If you are unhappy with the default, you can define the following CSS variable in your `custom-header.html` and set the value to your liking. If you want to use all available space, select a really big value like `1000rem`;
````css
:root {
--MAIN-WIDTH-MAX: 80.25rem;
}
````
## Own Shortcodes with JavaScript Dependencies
Certain shortcodes make use of additional JavaScript files. The theme only loads these dependencies if the shortcode is used. To do so correctly the theme adds management code in various files.
You can you use this mechanism in your own shortcodes. Say you want to add a shortcode `myshortcode` that also requires the `jquery` JavaScript library.
1. Write the shortcode file `layouts/shortcodes/myshortcode.html` and add the following line
````go
{{- .Page.Store.Set "hasMyShortcode" true }}
````
1. Add the following snippet to your `hugo.toml`
{{< multiconfig file=hugo >}}
[params.relearn.dependencies]
[params.relearn.dependencies.myshortcode]
name = "MyShortcode"
location = "footer"
{{< /multiconfig >}}
1. Add the dependency loader file `layouts/partials/dependencies/myshortcode.html`. The loader file will be appended to your header or footer, dependend on the `location` setting in your `hugo.toml`.
````html
<script src="https://www.unpkg.com/jquery/dist/jquery.js"></script>
````
Character casing is relevant!
- the `name` setting in your `hugo.toml` must match the key (that needs to be prefixed with a `has`) you used for the store in your `layouts/shortcodes/myshortcode.html`.
- the key on `params.relearn.dependencies` in your `hugo.toml` must match the base file name of your loader file.
See the `math`, `mermaid` and `openapi` shortcodes for examples.
## Output Formats
Certain parts of the theme can be changed for support of your own [output formats](https://gohugo.io/templates/output-formats/). Eg. if you define a new output format `PLAINTEXT` in your `hugo.toml`, you can add a file `layouts/partials/header.plaintext.html` to change the way, the page header should look like for that output format.
## React to Variant Switches in JavaScript
Once a color variant is fully loaded, either initially or by switching the color variant manually with the variant selector, the custom event `themeVariantLoaded` on the `document` will be dispatched. You can add an event listener and react to changes.
````javascript
document.addEventListener( 'themeVariantLoaded', function( e ){
console.log( e.detail.variant ); // `relearn-light`
});
````
## Partials
The Relearn theme has been built to be as configurable as possible by defining multiple [partials](https://gohugo.io/templates/partials/)
In `themes/hugo-theme-relearn/layouts/partials/`, you will find all the partials defined for this theme. If you need to overwrite something, don't change the code directly. Instead [follow this page](https://gohugo.io/themes/customizing/). You'd create a new partial in the `layouts/partials` folder of your local project. This partial will have the priority.
This theme defines the following partials :
- `header.html`: the header of the page. See [output-formats](#output-formats)
- `footer.html`: the footer of the page. See [output-formats](#output-formats)
- `body.html`: the body of the page. The body may contain of one or many articles. See [output-formats](#output-formats)
- `article.html`: the output for a single article, can contain elements around your content. See [output-formats](#output-formats)
- `menu.html`: left menu. _Not meant to be overwritten_
- `search.html`: search box. _Not meant to be overwritten_
- `custom-header.html`: custom headers in page. Meant to be overwritten when adding CSS imports. Don't forget to include `style` HTML tag directive in your file.
- `custom-footer.html`: custom footer in page. Meant to be overwritten when adding JavaScript. Don't forget to include `javascript` HTML tag directive in your file.
- `favicon.html`: the favicon
- `heading.html`: side-wide configuration to change the pages title headings.
- `heading-pre.html`: side-wide configuration to prepend to pages title headings. If you override this, it is your responsibility to take the page's `headingPre` setting into account.
- `heading-post.html`: side-wide configuration to append to pages title headings. If you override this, it is your responsibility to take the page's `headingPost` setting into account.
- `logo.html`: the logo, on top left hand corner
- `meta.html`: HTML meta tags, if you want to change default behavior
- `menu-pre.html`: side-wide configuration to prepend to menu items. If you override this, it is your responsibility to take the page's `menuPre` setting into account.
- `menu-post.html`: side-wide configuration to append to menu items. If you override this, it is your responsibility to take the page's `menuPost` setting into account.
- `menu-footer.html`: footer of the the left menu
- `toc.html`: table of contents
- `content.html`: the content page itself. This can be overridden if you want to display page's meta data above or below the content.
- `content-header.html`: header above the title, has a default implementation but you can overwrite it if you don't like it.
- `content-footer.html`: footer below the content, has a default implementation but you can overwrite it if you don't like it.

This interactive tool may help you to generate your own color variant stylesheet.
{{% expand "Show usage instructions" %}}
To get started, first select a color variant from the variant selector in the lower left sidebar that fits you best as a starting point.
The graph is interactive and reflect the current colors. You can click on any of the colored boxes to adjust the respective color. The graph **and the page** will update accordingly.
The arrowed lines reflect how colors are inherited thru different parts of the theme if the descendent isn't overwritten. If you want to delete a color and let it inherit from its parent, just delete the value from the input field.
To better understand this select the `neon` variant and modify the different heading colors. There, colors for the heading `h2`, `h3` and `h4` are explicitly set. `h5` is not set and inherits its value from `h4`. `h6` is also not set and inherits its value from `h5`.
Once you've changed a color, the variant selector will show a "My custom variant" entry and your changes are stored in the browser. You can **browse to other pages** and even close the browser **without losing your changes**.
Once you are satisfied, you can download the new variants file and copy it into your site's `static/css` directory. Afterwards you have to adjust the `themeVariant` parameter in your `hugo.toml` to your chosen file name.
Eg. if your new variants file is named `theme-my-custom-variant.css`, you have to set `themeVariant='my-custom-variant'` to use it.

The following steps are here to help you initialize your new website. If you don't know Hugo at all, we strongly suggest you learn more about it by following this [great documentation for beginners](https://gohugo.io/overview/quickstart/).
{{% notice tip %}}
The following tutorial leads you thru the steps of creating a first, minimal new site.
You don't need to edit any files besides your `hugo.toml` and only need to execute the commands in the given order.
{{% /notice %}}
## Create your project
Hugo provides a `new` command to create a new website:
````shell
hugo new site my-new-site
````
After that change into the directory:
````shell
cd my-new-site
````
Every upcoming command will be executed from inside your new site's root.
## Install the theme
### From Download
You can [download the theme as .zip](https://github.com/McShelby/hugo-theme-relearn/archive/main.zip) file and extract it into them `themes/hugo-theme-relearn` directory.
### With Hugo's Module System
Install the Relearn theme by following [this documentation](https://gohugo.io/hugo-modules/use-modules/#use-a-module-for-a-theme) using Hugo's module system.
This theme's repository is: https://github.com/McShelby/hugo-theme-relearn.git
### Using Git or Git Submodules
If you install the theme from your git repository or GitHub, you have several options.
If you use the `head` of the `main` branch, you are using the development version. Usually it is fully functional but can break from time to time. We try to fix newly introduced bugs in this version as soon as possible.
Additionally you can checkout one of the tagged versions. These tagged versions correspond to an official [releases from the GitHub repository](https://github.com/McShelby/hugo-theme-relearn/releases).
Besides the usual version tags (eg `1.2.3`) there are also tags for the main version (eg. `1.2.x`), major version (eg. `1.x`) and the latest (just `x`) released version making it easier for you to pin the theme to a certain version.
## Basic Configuration
When building the website, you can set a theme by using `--theme` option. However, we suggest you modify the configuration file `hugo.toml` and set the theme as the default.
{{< multiconfig file=hugo >}}
theme = "hugo-theme-relearn"
{{< /multiconfig >}}
## Create your Home Page
If you don't create a home page, yet, the theme will generate a placeholder text with instructions how to proceed.
Start your journey by filling the home page with content
````shell
hugo new --kind home _index.md
````
By opening the given file, you should see the property `archetype=home` on top, meaning this page is a home page. The Relearn theme provides [some archetypes](cont/archetypes) to create those skeleton files for your website.
Obviously you better should change the page's content.
## Create your First Chapter Page
Chapters are pages that contain other child pages. It has a special layout style and usually just contains the _title_ and a _brief abstract_ of the section.
````md
# Basics
Discover what this Hugo theme is all about and the core concepts behind it.
````
renders as
![A Chapter](chapter.png?width=60pc)
Begin by creating your first chapter page with the following command:
````shell
hugo new --kind chapter basics/_index.md
````
By opening the given file, you should see the property `archetype=chapter` on top, meaning this page is a _chapter_.
The `weight` number will be used to generate the subtitle of the chapter page, set the number to a consecutive value starting at 1 for each new chapter level.
## Create your First Content Pages
Then, create content pages inside the previously created chapter. Here are two ways to create content in the chapter:
````shell
hugo new basics/first-content.md
hugo new basics/second-content/_index.md
````
Feel free to edit those files by adding some sample content and replacing the `title` value in the beginning of the files.
## Launching the Website Locally
Launch by using the following command:
````shell
hugo serve
````
Go to `http://localhost:1313`
You should notice three things:
1. The home page contains some basic text.
2. You have a left-side **Basics** menu, containing two submenus with names equal to the `title` properties in the previously created files.
3. When you run `hugo serve` your page refreshes automatically when you change a content page. Neat!
## Build the Website
When your site is ready to deploy, run the following command:
````shell
hugo
````
A `public` folder will be generated, containing all content and assets for your website. It can now be deployed on any web server.
Now it's time to deploy your page by simply uploading your project to some webserver or by using one of [Hugo's many deployment options](https://gohugo.io/hosting-and-deployment/).

## 5.26.0 (2024-03-18) {#5260}
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The lazy loading of images is now configurable by using the new `lazy` [image effect](cont/imageeffects). The default value hasn't changed in comparison to older versions, you don't need to change anything.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} It is now possible to [adjust the max width of the main area](basics/customization#change-the-main-areas-max-width), eg. in case you want to use the full page width for your content.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Images and Codefences are now respecting [Hugo's Markdown attributes](https://gohugo.io/content-management/markdown-attributes/).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme has updated its Mermaid dependency to 10.6.0. This adds support for [block diagrams](shortcodes/mermaid#block-diagram).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} This release fixes a long outstanding bug where the page wasn't repositioning correctly when going forward or backward in your browser history.

## 5.25.0 (2024-02-29) {#5250}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} This release deprecates the [`attachments` shortcode](shortcodes/attachments) in favor of the new the [`resources` shortcode](shortcodes/resources).
If you are using Hugo below {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.123.0{{% /badge %}}, you don't need to change anything as the old shortcode still works (but may generate warnings).
Anyways, users are strongly advised to migrate as the `attachments` shortcode will not receive support anymore. Migration instructions are listed on the [`attachments` shortcode page](shortcodes/attachments#migration).
- {{% badge style="note" title=" " %}}Change{{% /badge %}} If you run Hugo with [GitInfo](https://gohugo.io/methods/page/gitinfo/) configured, the default page footer now prints out name, email address and date of the last commit. If you want to turn this off you either have to run Hugo without GitInfo (which is the default) or overwrite the `content-footer.html` partial.
## 5.24.0 (2024-02-28) {#5240}
- {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.112.4{{% /badge %}} This release requires a newer Hugo version.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The topbar button received a way to add text next to the icon. For this, the original `title` option was renamed to `hint` while the new `title` option is now displayed next to the icon.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The frontmatter option `menuTitle` is now deprecated in favor for Hugo's own `linkTitle`. You don't need to change anything as the old `menuTitle` option is still supported.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The light themes have a bit more contrast for content text and headings. Also the syntaxhighlighting was changed to the more colorful MonokaiLight. This brings the syntaxhighlightning in sync with the corresponding dark theme variants, which are using Monokai. If you dislike this, you can create your own color variant file as [described here](basics/branding#modify-shipped-variants).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} If the theme can not resolve a link to a page or image, you can now generate warnings or errors during build by setting `link.errorlevel` or `image.errorlevel` to either `warning` or `error` in your `hugo.toml` respectively. By default this condition is silently ignored and the link is written as-is.
Please note that a page link will generate false negatives if `uglyURLs=true` and it references an ordinary page before {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.123.0{{% /badge %}}.
Please note that an image link will generate false negatives if the file resides in your `static` directory.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} You now can configure additional options for every theme variant in your `hugo.toml`. This allows for optional [advanced functionality](basics/branding#theme-variant-advanced). You don't need to change anything as the old configuration options will still work (but may generate warnings now).
The advanced functionality allows you to set an explicit name for a theme variant and now allows for multiple auto mode variants that adjust to the light/dark preference of your OS settings.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} New partial for defining the heading. See [documentation](basics/customization#partials) for further reading.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Support for Hugo's built-in [`figure` shortcode](https://gohugo.io/content-management/shortcodes/#figure).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} On taxonomy and term pages you can now use prev/next navigation as within the normal page structure.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} In additiion to the existing [menu width customization](basics/customization#change-the-menu-width), it is now also possible to set the width of the menu flyout for small screen sizes with the `--MENU-WIDTH-S` CSS property.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Improvements for accessibility when tabbing thru the page for images, links and tab handles.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The `editURL` config parameter is now [overwritable in your pages frontmatter](cont/frontmatter). In addition it received more versatility by letting you control where to put the file path into the URL. This is achieved by replacing the variable `${FilePath}` in your URL by the pages file path. You don't need to change anything in your existing configuration as the old way without the replacement variable still works.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The themes [config](basics/configuration) and [frontmatter](cont/frontmatter) options received a comprehensive documentation update. In addition the theme switched from `config.toml` to `hugo.toml`.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Restored compatibility with Hugo versions {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.121.0{{% /badge %}} or higher for the [`highlight` shortcode](shortcodes/highlight). This does not change the minimum required Hugo version.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Restored compatibility with Hugo versions {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.123.0{{% /badge %}} or higher for theme specific [output formats](basics/customization) and handling of taxonomy and term titles. This does not change the minimum required Hugo version.

## 5.23.0 (2023-11-03) {#5230}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} With {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.120.0{{% /badge %}} the author settings move into the `[params]` array in your `hugo.toml`. Because this collides with the previous way, the theme expected author information, it now adheres to Hugo standards and prints out a warning during built if something is wrong.
Change your previous setting from
{{< multiconfig file=hugo >}}
[params]
author = "Hugo"
{{< /multiconfig >}}
to
{{< multiconfig file=hugo >}}
[params]
author.name = "Hugo"
{{< /multiconfig >}}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} Taxonomy [term pages](https://gohugo.io/content-management/taxonomies#add-custom-metadata-to-a-taxonomy-or-term) now add the breadcrumb for each listed page. If this gets too crowded for you, you can turn the breadcrumbs off in your `hugo.toml` by adding `disableTermBreadcrumbs=true`.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Taxonomy and term pages are now allowed to contain content. This is added inbetween the title and the page list.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} It is now possible to print custom taxonomies anywhere in your page. [See the docs](cont/taxonomy#customization).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} It is now possible to adjust the menu width for your whole site. [See the docs](basics/customization#change-the-menu-width).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} This release adds social media meta tags for the Open Graph protocol and Twitter Cards to your site. [See the docs](basics/customization#social-media-meta-tags).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} This release comes with additional sort options for the menu and the [`children` shortcode](shortcodes/children). Both will now accept the following values: `weight`, `title`, `linktitle`, `modifieddate`, `expirydate`, `publishdate`, `date`, `length` or `default` (adhering to Hugo's default sort order).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme now provides a mechanism to load further JavaScript dependencies defined by you only if it is needed. This comes in handy if you want to add own shortcodes that depend on additional JavaScript code to be loaded. [See the docs](basics/customization#own-shortcodes-with-javascript-dependencies).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme has updated its Mermaid dependency to 10.6.0. This adds support for the [xychart type](shortcodes/mermaid#xychart).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} This release adds portable Markdown links.
Previously it was not possible to use pure Markdown links in a configuration independend way to link to pages inside of your project. It always required you to know how your `uglyURLs` setting is, wheather you link to a page or page bundle and in case of relative links if your current page is a page or page bundle. (eg. `[generator](generator/index.html)` vs. `[generator](generator.html)`). This is a hassle as you have to change these links manually once you change your `uglyURLs` setting or change the type of a page.
You could work around this by using the `relref` shortcode (eg `[generator]({{%/* relref "../generator" */%}})`) which works but results in non-portable Markdown.
Now it's possible to use the same path of a call to `relref` in a plain Markdown link (eg `[generator](../generator)`). This is independend of any configuration settings or the page types involved in linking. Note, that this requires your links to be given without any extension, so `[generator](generator/index.html)` will work as before.
The following types of linking are supported:
| link | description |
| ---------------------------------- | ------------------------------------------- |
| `[generator](en/basics/generator)` | absolute from your project root (multilang) |
| `[generator](/en/basics/generator)`| absolute from your project root (multilang) |
| `[generator](basics/generator)` | absolute from your current language root |
| `[generator](/basics/generator)` | absolute from your current language root |
| `[generator](./../generator)` | relative from the current page |
| `[generator](../generator)` | relative from the current page |

## 5.22.0 (2023-10-02) {#5220}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} This release fixes an issue where in unfortunate conditions DOM ids generated by Hugo may collide with DOM ids set by the theme. To avoid this, all theme DOM ids are now prefixed with `R-`.
If you haven't modified anything, everything is fine. Otherwise you have to check your custom CSS rules and JavaScript code.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} You can now have structural sections in the hierarchical menu without generating a page for it.
This can come in handy, if content for such a section page doesn't make much sense to you. See [the documentation](cont/frontmatter#disable-section-pages) for how to do this.
This feature may require you to make changes to your existing installation if you are already using _[shortcuts to pages inside of your project](cont/menushortcuts#shortcuts-to-pages-inside-of-your-project)_ with a _headless branch parent_.
In this case it is advised to remove the `title` from the headless branch parent's frontmatter, as it will otherwise appear in your breadcrumbs.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} It is now possible to overwrite the setting for `collapsibleMenu` of your `hugo.toml` inside of a page's frontmatter.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} If a Mermaid graph is zoomable a button to reset the view is now added to the upper right corner. The button is only shown once the mouse is moved over the graph.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} It is now possible to remove the root breadcrumb by setting `disableRootBreadcrumb=true` in your `hugo.toml`.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The output of the dedicated search page now displays the result's breadcrumb.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Table rows now change their background color on every even row.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Translation into Swahili. This language is not supported for search.
---
## 5.21.0 (2023-09-18) {#5210}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} We made changes to the menu footer to improve alignment with the menu items in most cases. Care was taken not to break your existing overwritten footer. Anyways, if you have your `menu-footer.html` [partial overridden](basics/customization#partials), you may want to review the styling (eg. margins/paddings) of your partial.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} This release comes with an awesome new feature, that allows you to customize your topbar buttons, change behavior, reorder them or define entirely new ones, unique to your installation. See [the documentation](basics/topbar) for further details.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme has updated its Swagger dependency to 5.7.2 for the [`openapi` shortcode](shortcodes/openapi). This brings support for OpenAPI Specification 3.1.
---
## 5.20.0 (2023-08-26) {#5200}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The theme has updated its Swagger dependency to 5.4.1 for the [`openapi` shortcode](shortcodes/openapi).
With this comes a change in the light theme variants of `Relearn Bright`, `Relearn Light` and `Zen Light` by switching the syntaxhighlightning inside of openapi to a light scheme. This brings it more in sync with the code style used by the theme variants itself.
Additionally, the syntaxhighlightning inside of openapi for printing was switched to a light scheme for all theme variants.
If you dislike this change, you can revert this in your theme variants CSS by adding
````css
--OPENAPI-CODE-theme: obsidian;
--PRINT-OPENAPI-CODE-theme: obsidian;
````
- {{% badge style="note" title=" " %}}Change{{% /badge %}} For consistency reasons, we renamed the CSS variable `--MENU-SECTION-HR-color` to `--MENU-SECTION-SEPARATOR-color`. You don't need to change anything in your custom color stylesheet as the old name will be used as a fallback.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme variants `Zen Light` and `Zen Dark` now add more contrast between menu, topbar and content by adding thin borders.
Those borders are now configurable by using the CSS variables `--MAIN-TOPBAR-BORDER-color`, `--MENU-BORDER-color`, `--MENU-TOPBAR-BORDER-color`, `--MENU-TOPBAR-SEPARATOR-color`, `--MENU-HEADER-SEPARATOR-color` and `--MENU-SECTION-ACTIVE-CATEGORY-BORDER-color`.
For existing variants nothing has changed visually.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The default values for the [image effects](cont/markdown#image-effects) are [now configurable](cont/imageeffects) for your whole site via `hugo.toml` or for each page thru frontmatter.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} This release fixes a long outstanding bug where Mermaid graphs could not be displayed if they were initially hidden - like in collapsed `expand` or inactive `tabs`.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Restored compatibility with Hugo versions lower than {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.111.0{{% /badge %}} for the [`highlight` shortcode](shortcodes/highlight). This does not change the minimum required Hugo version.
---
## 5.19.0 (2023-08-12) {#5190}
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The [`highlight` shortcode](shortcodes/highlight) now accepts the new parameter `title`. This displays the code like a [single tab](shortcodes/tab). This is also available using codefences and makes it much easier to write nicer code samples.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme has added two new color variants `zen-light` and `zen-dark`. Check it out!
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme now [dispatches the custom event](basics/customization#react-to-variant-switches-in-javascript) `themeVariantLoaded` on the `document` when the variant is fully loaded either initially or by switching the variant manually with the variant selector.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme has updated its Mermaid dependency to 10.3.1. This adds support for the [sankey diagram type](shortcodes/mermaid#sankey) and now comes with full support for YAML inside Mermaid graphs (previously, the theme ignored explicit Mermaid theme settings in YAML).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Translation into Hungarian.
---
## 5.18.0 (2023-07-27) {#5180}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The theme adds additional warnings for deprecated or now unsupported features.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} There are visual improvements in displaying text links in your content aswell as to some other clickable areas in the theme. If you've overwritten some theme styles in your own CSS, keep this in mind.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Restored compatibility with Hugo {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.95.0{{% /badge %}} or higher. This does not change the minimum required Hugo version.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The [`siteparam` shortcode](shortcodes/siteparam) is now capable in displaying nested params aswell as supporting text formatting.
---
## 5.17.0 (2023-06-22) {#5170}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The default behavior for the copy-to-clipboard feature for code blocks has changed.
The copy-to-clipboard button for code blocks will now only be displayed if the reader hovers the code block.
If you dislike this new behavior you can turn it off and revert to the old behavior by adding `[params] disableHoverBlockCopyToClipBoard=true` to your `hugo.toml`.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Restored compatibility with Hugo {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.114.0{{% /badge %}} or higher. This does not change the minimum required Hugo version.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The new [`highlight` shortcode](shortcodes/highlight) replaces Hugo's default implementation and is fully compatible. So you don't need to change anything.
In addition it offers some extensions. Currently only the `wrap` extension option is provided to control whether a code block should be wrapped or scrolled if to long to fit.
---
## 5.16.0 (2023-06-10) {#5160}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The theme now provides warnings for deprecated or now unsupported features. The warnings include hints how to fix them and an additional link to the documentation.
`DEPRECATION` warnings mark features that still work but may be removed in the future.
`UNSUPPORTED` warnings mark features that will not work anymore.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The 404 error page was revamped. Hopefully you will not see this very often.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The [`tabs` shortcode](shortcodes/tabs) and the [`tab` shortcode](shortcodes/tab) received some love and now align with their style, color, title and icon parameter to the other shortcodes.
The visuals are now slightly different compared to previous versions. Most noteable, if you now display a single code block in a tab, its default styling will adapt to that of a code block but with a tab handle at the top.
Additionally the `name` parameter was renamed to `title` but you don't need to change anything yet as the old name will be used as a fallback. Nevertheless you will get deprecation warnings while executing Hugo.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme now optionally supports [separate favicons](basics/customization#change-the-favicon) for light & dark mode.
---
## 5.15.0 (2023-05-29) {#5150}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} Restored compatibility with Hugo {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.112.0{{% /badge %}} or higher. This does not change the minimum required Hugo version.
The [`attachments` shortcode](shortcodes/attachments) has compatibility issues with newer Hugo versions. You must switch to leaf bundles or are locked to Hugo < `0.112.0` for now.
It is [planned to refactor](https://github.com/McShelby/hugo-theme-relearn/issues/22) the `attchments` shortcode in the future. This will make it possible to use the shortcode in branch bundles again but not in simple pages anymore. This will most likely come with a breaking change.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The [`tabs` shortcode](shortcodes/tabs) has changed behavior if you haven't set the `groupid` parameter.
Formerly all tab views without a `groupid` were treated as so they belong to the same group. Now, each tab view is treated as it was given a unique id.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The already known `tabs`has a new friend the [`tab` shortcode](shortcodes/tab) to make it easier to create a tab view in case you only need one single tab. Really handy if you want to flag your code examples with a language identifier.
Additionally for such a use case, the whitespace between a tab outline and the code is removed if only a single code block is contained.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Besides the _tag_ [taxonomy](cont/taxonomy) the theme now also provides the _category_ taxonomy out of the box and shows them in the content footer of each page.
---
## 5.14.0 (2023-05-20) {#5140}
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The taxonomy pages received some love in this release, making them better leverage available screen space and adding translation support for the taxonomy names.
Hugo's default taxonmies `tags` and `categories` are already contained in the theme's i18n files. If you have self-defined taxonomies, you can add translations by adding them to your own i18n files. If you don't provide translations, the singualar and plural forms are taken as configured in your `hugo.toml`.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} To give you more flexibility in customizing your article layout a new partial `content-header.html` is introduced.
This came out of the requirement to customize the position of article tags, which by default are displayed above the title. A second requirement was to also show additional [taxonomies](https://gohugo.io/content-management/taxonomies/) not supported by the theme natively. While Hugo supports tags and categories by default, the theme only displays tags.
So how to adjust the position of tags starting from the theme's default where tags are only shown above the title?
1. Hide tags above title: Overwrite `content-header.html` with an empty file.
2. Show tags between title and content: Overwrite `heading-post.html` and add `{{ partial "tags.html" . }}` to it.
3. Show tags below content: Overwrite `content-footer.html` and add `{{ partial "tags.html" . }}` to it.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The new parameter `breadcrumbSeparator` is now available in your `hugo.toml` to change the - well - separator of the breadcrumb items. An appropriate default is in place if you do not configure anything.
---
## 5.13.0 (2023-05-17) {#5130}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The `swagger` shortcode was deprecated in favor for the [`openapi` shortcode](shortcodes/openapi). You don't need to change anything yet as the old name will be used as a fallback. It is planned to remove the `swagger` shortcode in the next major release.
Additionally, the implemantion of this shortcode was switched from RapiDoc to [SwaggerUI](https://github.com/swagger-api/swagger-ui).
---
## 5.12.0 (2023-05-04) {#5120}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} In the effort to comply with WCAG standards, the implementation of the collapsible menu was changed (again). While Internet Explorer 11 has issues in displaying it, the functionality still works.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Support for the great [VSCode Front Matter extension](https://github.com/estruyf/vscode-front-matter) which provides on-premise CMS capabilties to Hugo.
The theme provides Front Matter snippets for its shortcodes. Currently only English and German is supported. Put a reference into your `frontmatter.json` like this
````json {title="frontmatter.json"}
{
...
"frontMatter.extends": [
"./vscode-frontmatter/snippets.en.json"
]
...
}
````
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Support for languages that are written right to left (like Arabic) is now complete and extended to the menu, the top navigation bar and print. You can experience this in the [pirate translation](/pir). This feature is not available in Internet Explorer 11.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The scrollbars are now colored according to their variant color scheme to better fit into the visuals.
---
## 5.11.0 (2023-02-07) {#5110}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The theme removed the popular [jQuery](https://jquery.com) library from its distribution.
In case you made changes to the theme that are dependend on this library you can place a copy of jQuery into your `static/js` directory and load it from your own `layouts/partials/custom-header.html` like this:
````html {title="layouts/partials/custom-header.html"}
<script src="{{"js/jquery.min.js"| relURL}}" defer></script>
````
- {{% badge style="note" title=" " %}}Change{{% /badge %}} [Mermaid](shortcodes/mermaid#parameter) diagrams can now be configured for pan and zoom on site-, page-level or individually for each graph.
The default setting of `on`, in effect since 1.1.0, changed back to `off` as there was interference with scrolling on mobile and big pages.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The theme is now capable to visually [adapt to your OS's light/dark mode setting](basics/branding#adjust-to-os-settings).
This is also the new default setting if you haven't configured `themeVariant` in your `hugo.toml`.
Additionally you can configure the variants to be taken for light/dark mode with the new `themeVariantAuto` parameter.
This is not supported for Internet Explorer 11, which still displays in the `relearn-light` variant.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The JavaScript code for handling image lightboxes (provided by [Featherlight](https://noelboss.github.io/featherlight)) was replaced by a CSS-only solution.
This also changed the [lightbox effects](cont/markdown#lightbox) parameter from `featherlight=false` to `lightbox=false`. Nevertheless you don't need to change anything as the old name will be used as a fallback.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} In the effort to comply with WCAG standards, the implementation of the [`expand` shortcode](shortcodes/expand) was changed. While Internet Explorer 11 has issues in displaying it, the functionality still works.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Translation into Czech. This language is not supported for search.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} [GitHub releases](https://github.com/McShelby/hugo-theme-relearn/tags) are also now tagged for the main version (eg. `1.2.x`), major version (eg. `1.x`) and the latest (just `x`) release making it easier for you to pin the theme to a certain version.
---
## 5.10.0 (2023-01-25) {#5100}
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The [`attachments`](shortcodes/attachments), [`badge`](shortcodes/badge), [`button`](shortcodes/button) and [`notice`](shortcodes/notice) shortcodes have a new parameter `color` to set arbitrary CSS color values.
Additionally the `--ACCENT-color` brand color introduced in version 5.8.0 is now supported with these shortcodes.
---
## 5.9.0 (2022-12-23) {#590}
- {{% badge style="warning" title=" " %}}Breaking{{% /badge %}} With this version it is now possible to not only have sections on the first menu level but also pages.
It was later discovered, that this causes pages only meant to be displayed in the `More` section of the menu and stored directly inside your `content` directory to now show up in the menu aswell.
To [get rid](cont/menushortcuts#shortcuts-to-pages-inside-of-your-project) of this undesired behavior you have two choices:
1. Make the page file a [headless branch bundle](https://gohugo.io/content-management/page-bundles/#headless-bundle) (contained in its own subdirectory and called `_index.md`) and add the following frontmatter configuration to the file (see exampleSite's `content/showcase/_index.en.md`). This causes its content to **not** be ontained in the sitemap.
{{< multiconfig fm=true >}}
title = "Showcase"
[_build]
render = "always"
list = "never"
publishResources = true
{{< /multiconfig >}}
2. Store the page file for below a parent headless branch bundle and add the following frontmatter to he **parent** (see exampleSite's `content/more/_index.en.md`). **Don't give this page a `title`** as this will cause it to be shown in the breadcrumbs - a thing you most likely don't want.
{{< multiconfig fm=true >}}
[_build]
render = "never"
list = "never"
publishResources = false
{{< /multiconfig >}}
In this case, the file itself can be a branch bundle, leaf bundle or simple page (see exampleSite's `content/more/credits.en.md`). This causes its content to be contained in the sitemap.
{{< multiconfig fm=true >}}
title = "Credits"
{{< /multiconfig >}}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The required folder name for the [`attachments` shortcode](shortcodes/attachments) was changed for leaf bundles.
Previously, the attachments for leaf bundles in non-multilang setups were required to be in a `files` subdirectory. For page bundles and leaf bundles in multilang setups they were always required to be in a `_index.<LANGCODE>.files` or `index.<LANGCODE>.files` subdirectory accordingly.
This added unnecessary complexity. So attachments for leaf bundles in non-multilang setups can now also reside in a `index.files` directory. Although the old `files` directory is now deprecated, if both directories are present, only the old `files` directory will be used for compatibility.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} Absolute links prefixed with `http://` or `https://` are now opened in a separate browser tab.
You can revert back to the old behavior by defining `externalLinkTarget="_self"` in the `params` section of your `hugo.toml`.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme now supports [Hugo's module system](https://gohugo.io/hugo-modules/).
---
## 5.8.0 (2022-12-08) {#580}
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The new [`badge` shortcode](shortcodes/badge) is now available to add highly configurable markers to your content as you can see it on this page.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The new [`icon` shortcode](shortcodes/icon) simplyfies the usage of icons. This can even be combined with also new `badge` shortcode.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme now supports some of GFM (GitHub Flavored Markdown) syntax and Hugo Markdown extensions, namely [task lists](cont/markdown#tasks), [defintion lists](cont/markdown#defintions) and [footnotes](cont/markdown#footnotes).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} A new color `--ACCENT-color` was introduced which is used for highlightning search results on the page. In case you simply don't care, you don't need to change anything in your variant stylesheet as the old `yellow` color is still used as default.
---
## 5.7.0 (2022-11-29) {#570}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The Korean language translation for this theme is now available with the language code `ko`. Formerly the country code `kr` was used instead.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The [`button` shortcode](shortcodes/button) can now also be used as a real button inside of HTML forms - although this is a pretty rare use case. The documentation was updated accordingly.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The search now supports the Korean language.
---
## 5.6.0 (2022-11-18) {#560}
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} This release introduces an additional dedicated search page. On this page, displayed search results have more space making it easier scanning thru large number of results.
To activate this feature, you need to [configure it](basics/customization#activate-dedicated-search-page) in your `hugo.toml` as a new outputformat `searchpage` for the home page. If you don't configure it, no dedicated search page will be accessible and the theme works as before.
You can access the search page by either clicking on the magnifier glass or pressing enter inside of the search box.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Keyboard handling for the TOC and search was improved.
Pressing `CTRL+ALT+t` now will not only toggle the TOC overlay but also places the focus to the first heading on opening. Subsequently this makes it possible to easily select headings by using the `TAB` key.
The search received its own brand new keyboard shortcut `CTRL+ALT+f`. This will focus the cursor inside of the the search box so you can immediately start your search by typing.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} You are now able to turn off the generation of generator meta tags in your HTML head to hide the used versions of Hugo and this theme.
To [configure this](basics/configuration) in your `hugo.toml` make sure to set Hugo's `disableHugoGeneratorInject=true` **and** also `[params] disableGeneratorVersion=true`, otherwise Hugo will generate a meta tag into your home page automagically.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Creation of your project gets a little bit faster with this release.
This addresses increased build time with the 5.x releases. The theme now heavily caches partial results leading to improved performance. To further increase performance, unnecessary parts of the page are now skipped for creation of the print output (eg. menus, navigation bar, etc.).
---
## 5.5.0 (2022-11-06) {#550}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The way images are processed has changed. Now images are lazy loaded by default which speeds up page load on slow networks and/or big pages and also the print preview.
For that the JavaScript code to handle the [lightbox and image effects](cont/markdown#image-effects) on the client side was removed in favour for static generation of those effects on the server.
If you have used HTML directly in your Markdown files, this now has the downside that it doesn't respect the effect query parameter anymore. In this case you have to migrate all your HTML `img` URLs manually to the respective HTML attributes.
| Old | New |
|--------------------------------------------------------|-----------------------------------------------------------------|
| `<img src="pic.png?width=20vw&classes=shadow,border">` | `<img src="pic.png" style="width:20vw;" class="shadow border">` |
---
## 5.4.0 (2022-11-01) {#540}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} [With the proper settings](basics/customization#file-system) in your `hugo.toml` your page is now servable from the local file system using `file://` URLs.
Please note that the searchbox will only work for this if you reconfigure your outputformat for the homepage in your `hugo.toml` from `json` to `search`. The now deprecated `json` outputformat still works as before, so there is no need to reconfigure your installation if it is only served from `http://` or `https://`.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The [`button` shortcode](shortcodes/button) has a new parameter `target` to set the destination frame/window for the URL to open. If not given, it defaults to a new window/tab for external URLs or is not set at all for internal URLs. Previously even internal URLs where opened in a new window/tab.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The [`math` shortcode](shortcodes/math) and [`mermaid` shortcode](shortcodes/mermaid) now also support the `align` parameter if codefence syntax is used.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Support for languages that are written right to left (like Arabic). This is only implemented for the content area but not the navigation sidebar. This feature is not available in Internet Explorer 11.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Translation into Finnish (Suomi).
---
## 5.3.0 (2022-10-07) {#530}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} In the effort to comply with WCAG standards, the implementation of the collapsible menu was changed. The functionality of the new implementation does not work with old browsers (Internet Explorer 11).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} [Image formatting](cont/markdown#add-css-classes) has two new classes to align images to the `left` or `right`. Additionally, the already existing `inline` option is now documented.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Printing for the [`swagger` shortcode](shortcodes/openapi) was optimized to expand sections that are usually closed in interactive mode. This requires [print support](basics/customization#activate-print-support) to be configured.
---
## 5.2.0 (2022-08-03) {#520}
- {{% badge style="note" title=" " %}}Change{{% /badge %}} If you've set `collapsibleMenu = true` in your `hugo.toml`, the menu will be expanded if a search term is found in a collapsed submenu. The menu will return to its initial collapse state once the search term does not match any submenus.
---
## 5.1.0 (2022-07-15) {#510}
- {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.95.0{{% /badge %}} This release requires a newer Hugo version.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} Because the print preview URLs were non deterministic for normal pages in comparison to page bundles, this is now changed. Each print preview is now accessible by adding a `index.print.html` to the default URL.
You can revert this behavior by overwriting the `print` output format setting in your `hugo.toml`to:
{{< multiconfig file=hugo >}}
[outputFormats]
[outputFormats.print]
name= "print"
baseName = "index"
path = "_print"
isHTML = true
mediaType = 'text/html'
permalinkable = false
{{< /multiconfig >}}
---
## 5.0.0 (2022-07-05) {#500}
- {{% badge style="warning" title=" " %}}Breaking{{% /badge %}} The theme changed how JavaScript and CSS dependencies are loaded to provide a better performance. In case you've added own JavaScript code that depends on the themes jQuery implementation, you have to put it into a separate `*.js` file (if not already) and add the `defer` keyword to the `script` element. Eg.
````html
<script defer src="myscript.js"></script>
````
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The way [archetypes](cont/archetypes) are used to generate output has changed. The new systems allows you, to redefine existing archetypes or even generate your own ones.
Your existing markdown files will still work like before and therefore you don't need to change anything after the upgrade. Nevertheless, it is recommended to adapt your existing markdown files to the new way as follows:
- for your home page, add the frontmatter parameter `archetype = "home"` and remove the leading heading
- for all files containing the deprecated frontmatter parameter `chapter = true`, replace it with `archetype = "chapter"` and remove the leading headings
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The frontmatter options `pre` / `post` were renamed to `menuPre` / `menuPost`. The old options will still be used if the new options aren't set. Therefore you don't need to change anything after the upgrade.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Adding new partials `heading-pre.html` / `heading-post.html` and according frontmatter options `headingPre` / `headingPost` to modify the way your page`s main heading gets styled.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The new shortcode `math` is available to add beautiful math and chemical formulae. See the [documentation](shortcodes/math) for available features. This feature will not work with Internet Explorer 11.
---
## 4.2.0 (2022-06-23) {#420}
- {{% badge style="warning" title=" " %}}Breaking{{% /badge %}} The second parameter for the [`include` shortcode](shortcodes/include) was switched in meaning and was renamed from `showfirstheading` to `hidefirstheading`. If you haven't used this parameter in your shortcode, the default behavior hasn't changed and you don't need to change anything.
If you've used the second boolean parameter, you have to rename it and invert its value to achieve the same behavior.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} Previously, if the [`tabs` shortcode](shortcodes/tabs) could not find a tab item because, the tabs ended up empty. Now the first tab is selected instead.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The `landingPageURL` was removed from `hugo.toml`. You can safely remove this as well from your configuration as it is not used anymore. The theme will detect the landing page URL automatically and will point to the project's homepage. If you want to support a different link, overwrite the `logo.html` partial.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} All shortcodes can now be also called from your partials. Examples for this are added to the documentation of each shortcode.

## 4.1.0 (2022-06-12) {#410}
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} While fixing issues with the search functionality for non Latin languages, you can now [configure to have multiple languages on a single page](cont/i18n#search-with-mixed-language-support).
---
## 4.0.0 (2022-06-05) {#400}
- {{% badge style="warning" title=" " %}}Breaking{{% /badge %}} The `custom_css` config parameter was removed from the configuration. If used in an existing installation, it can be achieved by overriding the `custom-header.html` template in a much more generic manner.
- {{% badge style="warning" title=" " %}}Breaking{{% /badge %}} Because anchor hover color was not configurable without introducing more complexity to the variant stylesheets, we decided to remove `--MAIN-ANCHOR-color` instead. You don't need to change anything in your custom color stylesheet as the anchors now get their colors from `--MAIN-LINK-color` and `--MAIN-ANCHOR-HOVER-color` respectively.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} All shortcodes now support named parameter. The positional parameter are still supported but will not be enhanced with new features, so you don't need to change anything in your installation.
This applies to [`expand`](shortcodes/expand), [`include`](shortcodes/include), [`notice`](shortcodes/notice) and [`siteparam`](shortcodes/siteparam).
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The [`button`](shortcodes/button) shortcode received some love and now has a parameter for the color style similar to other shortcodes.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} New colors `--PRIMARY-color` and `--SECONDARY-color` were added to provide easier modification of your custom style. Shortcodes with a color style can now have `primary` or `secondary` as additional values.
These two colors are the default for other, more specific color variables. You don't need to change anything in your existing custom color stylesheets as those variables get reasonable default values.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Translation into Polish. This language is not supported for search.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The documentation for all shortcodes were revised.

## 3.4.0 (2022-04-03) {#340}
- {{% badge style="warning" title=" " %}}Breaking{{% /badge %}} If you had previously overwritten the `custom-footer.html` partial to add visual elements below the content of your page, you have to move this content to the new partial `content-footer.html`. `custom-footer.html` was never meant to contain HTML other than additional styles and JavaScript.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} If you prefer expandable/collapsible menu items, you can now set `collapsibleMenu=true` in your `hugo.toml`. This will add arrows to all menu items that contain sub menus. The menu will expand/collapse without navigation if you click on an arrow.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} You can activate [print support](basics/customization#activate-print-support) in your `hugo.toml` to add the capability to print whole chapters or even the complete site.

## 3.3.0 (2022-03-28) {#330}
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Introduction of new CSS variables to set the font. The theme distinguishes between `--MAIN-font` for all content text and `--CODE-font` for inline or block code. There are additional overrides for all headings. See the [theme variant generator](basics/generator) of the exampleSite for all available variables.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The new shortcode `swagger` is available to include a UI for REST OpenAPI specifications. See the [documentation](shortcodes/openapi) for available features. This feature will not work with Internet Explorer 11.
---
## 3.2.0 (2022-03-19) {#320}
- {{% badge color="fuchsia" icon="fab fa-hackerrank" title=" " %}}0.93.0{{% /badge %}} This release requires a newer Hugo version.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} In this release the Mermaid JavaScript library will only be loaded on demand if the page contains a Mermaid shortcode or is using Mermaid codefences. This changes the behavior of `disableMermaid` config option as follows: If a Mermaid shortcode or codefence is found, the option will be ignored and Mermaid will be loaded regardlessly.
The option is still useful in case you are using scripting to set up your graph. In this case no shortcode or codefence is involved and the library is not loaded by default. In this case you can set `disableMermaid=false` in your frontmatter to force the library to be loaded. See the [theme variant generator](basics/generator) of the exampleSite for an example.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} Additional color variant variable `--MERMAID-theme` to set the variant's Mermaid theme. This causes the Mermaid theme to switch with the color variant if it defers from the setting of the formerly selected color variant.
---
## 3.1.0 (2022-03-15) {#310}
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} [`attachment`](shortcodes/attachments) and [`notice`](shortcodes/notice) shortcodes have a new parameter to override the default icon. Allowed values are all [Font Awesome 5 Free](https://fontawesome.com/v5/search?m=free) icons.
---
## 3.0.0 (2022-02-22) {#300}
- {{% badge style="warning" title=" " %}}Breaking{{% /badge %}} We made changes to the menu footer. If you have your `menu-footer.html` [partial overridden](basics/customization#partials), you may have to review the styling (eg. margins/paddings) in your partial. For a reference take a look into the `menu-footer.html` partial that is coming with the exampleSite.
This change was made to allow your own menu footer to be placed right after the so called prefooter that comes with the theme (containing the language switch and _Clear history_ functionality).
- {{% badge style="warning" title=" " %}}Breaking{{% /badge %}} We have changed the default colors from the original Learn theme (the purple menu header) to the Relearn defaults (the light green menu header) as used in the official documentation.
This change will only affect your installation if you've not set the `themeVariant` parameter in your `hugo.toml`. [If you still want to use the Learn color variant](basics/branding#theme-variant), you have to explicitly set `themeVariant="learn"` in your `hugo.toml`.
Note, that this will also affect your site if viewed with Internet Explorer 11 but in this case it can not be reconfigured as Internet Explorer does not support CSS variables.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} Due to a bug, that we couldn't fix in a general manner for color variants, we decided to remove `--MENU-SEARCH-BOX-ICONS-color` and introduced `--MENU-SEARCH-color` instead. You don't need to change anything in your custom color stylesheet as the old name will be used as a fallback.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} For consistency reasons, we renamed `--MENU-SEARCH-BOX-color` to `--MENU-SEARCH-BORDER-color`. You don't need to change anything in your custom color stylesheet as the old name will be used as a fallback.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} With this release you are now capable to define your own _dark mode_ variants.
To make this possible, we have introduced a lot more color variables you can use in [your color variants](basics/branding#theme-variant). Your old variants will still work and don't need to be changed as appropriate fallback values are used by the theme. Nevertheless, the new colors allow for much more customization.
To see what's now possible, see the new variants `relearn-dark` and `neon` that are coming with this release.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} To make the creation of new variants easier for you, we've added a new interactive [theme variant generator](basics/generator). This feature will not work with Internet Explorer 11.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} You can now configure multiple color variants in your `hugo.toml`. In this case, the first variant is the default chosen on first view and a variant selector will be shown in the menu footer. See the [documentation](basics/branding#multiple-variants) for configuration.
Note, that the new variant selector will not work with Internet Explorer 11 as it does not support CSS variables. Therefore, the variant selector will not be displayed with Internet Explorer 11.

## 2.9.0 (2021-11-19) {#290}
- {{% badge style="warning" title=" " %}}Breaking{{% /badge %}} This release removes the themes implementation of `ref`/`relref` in favor for Hugos standard implementation. This is because of inconsistencies with the themes implementation. In advantage, your project becomes standard compliant and exchanging this theme in your project to some other theme will be effortless.
In a standard compliant form you must not link to the `*.md` file but to its logical name. You'll see, referencing other pages becomes much easier. All three types result in the same reference:
| Type | Non-Standard | Standard |
|---------------|----------------------------------|------------------------|
| Branch bundle | `basics/configuration/_index.md` | `basics/configuration` |
| Leaf bundle | `basics/configuration/index.md` | `basics/configuration` |
| Page | `basics/configuration.md` | `basics/configuration` |
If you've linked from a page of one language to a page of another language, conversion is a bit more difficult but [Hugo got you covered](https://gohugo.io/content-management/cross-references/#link-to-another-language-version) as well.
Also, the old themes implementation allowed refs to non-existing content. This will cause Hugos implementation to show the error below and abort the generation. If your project relies on this old behavior, you can [reconfigure the error handling](https://gohugo.io/content-management/cross-references/#link-to-another-language-version) of Hugos implementation.
In the best case your usage of the old implementation is already standard compliant and you don't need to change anything. You'll notice this very easily once you've started `hugo server` after an upgrade and no errors are written to the console.
You may see errors on the console after the update in the form:
````shell
ERROR 2021/11/19 22:29:10 [en] REF_NOT_FOUND: Ref "basics/configuration/_index.md": "hugo-theme-relearn\exampleSite\content\_index.en.md:19:22": page not found
````
In this case, you must apply one of two options:
1. Start up a text editor with regular expression support for search and replace. Search for `(ref\s+"[^"]*?)(?:/_index|/index)?(?:\.md)?(#[^"]*?)?"` and replace it by `$1$2"` in all `*.md` files. **This is the recommended choice**.
2. Copy the old implementation files `theme/hugo-theme-relearn/layouts/shortcode/ref.html` and `theme/hugo-theme-relearn/layouts/shortcode/relref.html` to your own projects `layouts/shortcode/ref.html` and `layouts/shortcode/relref.html` respectively. **This is not recommended** as your project will still rely on non-standard behavior afterwards.

+++
The theme comes with a reasonably configured topbar.
![Topbar on mobile devices](topbar-closed.png)
Nevertheless, your requirements may differ from this configuration. Luckily the theme got you covered as the themebar, its buttons and the functionality behind these buttons is fully configurable by you.
{{% notice tip %}}
All mentioned file names below can be clicked and show you the implementation for a better understanding.
{{% /notice %}}
## Areas
The default configuration comes with three predefined areas that may contain an arbitrary set of buttons.
![Topbar with default areas marked](topbar-areas.png)
- [**start**](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/area/start.html): shown between menu and breadcrumb
- [**end**](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/area/end.html): shown on the opposite breadcrumb side in comparison to the _start_ area
- [**more**](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/area/more.html): shown when pressing the {{% button style="transparent" icon="ellipsis-v" %}}{{% /button %}} _more_ button in the topbar
While you can not add additional areas in the topbar, you are free to configure addtional buttons that behave like the _more_ button, providing further user defined areas.
## Buttons
The theme ships with the following predefined buttons (from left to right in the screenshot)
- {{% button style="transparent" icon="bars" %}}{{% /button %}} [**sidebar**](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/button/sidebar.html): opens the sidebar flyout if in mobile layout
- {{% button style="transparent" icon="list-alt" %}}{{% /button %}} [**toc**](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/button/toc.html): opens the table of contents in an overlay
- {{% button style="transparent" icon="pen" %}}{{% /button %}} [**edit**](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/button/edit.html): browses to the editable page if the `editURL` [parameter is set](basics/configuration)
- {{% button style="transparent" icon="print" %}}{{% /button %}} [**print**](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/button/print.html): browses to the chapters printable page if [print support](basics/customization#activate-print-support) was activated
- {{% button style="transparent" icon="chevron-left" %}}{{% /button %}} [**prev**](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/button/prev.html): browses to the previous page if there is one
- {{% button style="transparent" icon="chevron-right" %}}{{% /button %}} [**next**](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/button/next.html): browses to the next page if there is one
- {{% button style="transparent" icon="ellipsis-v" %}}{{% /button %}} [**more**](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/button/more.html): opens the overlay for the _more_ area
Not all buttons are displayed at every given time. This is configurable (see below if interested).
## Redefining Areas
Each predefined area and button comes in their own file. By that it is easy for you to overwrite an area file in your installation reusing only the buttons you like.
Eg. you can redefine the predefined _end_ area by adding the file [`layouts/partials/topbar/area/end.html`](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/area/end.html) in your installation (not in the theme itself) to remove all but the _more_ button.
The below example sets an explicit value for the `onempty` parameter, overriding the specific default value for this button (these defaults vary depending on the button). The parameter causes the _more_ button to always be displayed instead of hiding once its content is empty.
````go
{{ partial "topbar/button/more.html" (dict
"page" .
"onempty" "disable"
)}}
````
## Defining own Buttons
### Button Types
The theme distingushies between two types of buttons:
- [**button**](#button): a clickable button that either browses to another site, triggers a user defined script or opens an overlay containing user defined content
- [**area-button**](#area-button): the template for the {{% button style="transparent" icon="ellipsis-v" %}}{{% /button %}} _more_ button, to define your own area overlay buttons
### Button Parameter
#### Screen Widths and Actions
Depending on the screen width you can configure how the button should behave. Screen width is divided into three classes:
- **s**: (controlled by the `onwidths` parameter) mobile layout where the menu sidebar is hidden
- **m**: (controlled by the `onwidthm` parameter) desktop layout with visible sidebar while the content area width still resizes
- **l**: (controlled by the `onwidthl` parameter) desktop layout with visible sidebar once the content area reached its maximum width
For each width class, you can configure one of the following actions:
- `show`: the button is displayed in its given area
- `hide`: the button is removed
- `area-XXX`: the button is moved from its given area into the area `XXX`; eg. this is used to move buttons to the _more_ area overlay in the mobile layout
#### Hiding and Disabling Stuff
While hiding a button dependend on the screen size can be configured with the above described _hide_ action, you may want to hide the button on certain other conditions aswell.
For example, the _print_ button in its default configuration should only be displayed if print support was configured. This is done in your button template by checking the conditions first before displaying the button (see [`layouts/partials/topbar/button/print.html`](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/button/print.html)).
Another prefered condition for hiding a button is, if the displayed overlay is empty. This is the case for the _toc_ (see [`layouts/partials/topbar/button/toc.html`](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/button/toc.html)) aswell as the _more_ button (see [`layouts/partials/topbar/button/more.html`](https://github.com/McShelby/hugo-theme-relearn/blob/main/layouts/partials/topbar/button/more.html)) and controlled by the parameter `onempty`.
This parameter can have one of the following values:
- `disable`: the button displayed in disabled state if the overlay is empty
- `hide`: the button is removed if the overlay is empty
If you want to disable a button containing _no overlay_, this can be achieved by an empty `href` parameter. An example can be seen in the _prev_ button (see `layouts/partials/topbar/button/prev.html`) where the URL for the previous site may be empty.
## Reference
