Theme Assets

Theme assets are files that are referenced inside our main index.hbs file, therefore, must be copied over to the final generated directories.

Since we want to use Bootstrap to make our theme responsive, we need to do a few things:

1. Head over to Bootstrap's download page and download the minified CSS and JS files.
2. Unzip the file and copy /js/bootstrap.bundle.min.js to the js directory of our theme.
3. Create a folder named css in our theme root directory and copy /css/bootstrap.min.css into it.
4. Add the css directory in assets array inside config.json to declare the css directory as a theme asset.
5. Download JQuery and copy jquery-3.4.1.min.js to the js directory (your JQuery version might be different.)

All theme assets will be copied to the /assets/theme directory at the root of the documentation, therefore, all links inside index.hbs must be referenced by {{rootPrefix}}/assets/theme/ followed by the desired path. With that in mind, let's load Bootstrap and JQuery inside index.hbs's head tag:

...
{{#if extended.theme-color}}<meta name="theme-color" content="{{extended.theme-color}}">{{/if}}

{{! Load JQuery }}
<script src="{{rootPrefix}}/assets/theme/jquery-3.4.1.min.js"></script>

{{! Load Bootstrap }}
<link rel="stylesheet" href="{{rootPrefix}}/assets/theme/css/bootstrap.min.css">
<script src="{{rootPrefix}}/assets/theme/js/bootstrap.bundle.min.js" charset="utf-8"></script>

{{! Load theme's compiled SASS }}
<link rel="stylesheet" href="{{rootPrefix}}/assets/theme/styles.css">
...

Just like with the markdown content, there are two variables available to index.hbs:

• {{rootPrefix}}: Used for prefixing all links to the root directory of the documentation.
• {{versionRootPrefix}}: Used for prefixing all links to the root directory of the current version of the documentation.

Since both theme assets and user assets are copied to the root directory and are shared in all versions of the documentation, we should use {{rootPrefix}} whenever we're referencing any of them.

User Assets

Themes can extend the Fluorite configuration through themeOptions. Normally, any data the user defines under themeOptions will be passed to the template API as the extended object (which will be covered soon), but in some cases themes may want to let the user input some files (favicon, manifest, etc.) which needs some special handling. Since those files need to be copied into the generated documentation, we can declare those themeOptions extensions as user assets inside our theme configuration file.

Replace the userAssets object in config.json with the following values:

{
  "favicon-ico": "images/"
}

The above configuration tells Fluorite to copy the file provided in flconfig.json's themeOptions['favicon-ico'] to the /assets/user/images directory. We can access this file through the template API's extended['favicon-ico'] inside our Handlebars template.

Your final theme config should look like the following:

config.json:

{
  "hasFlavors": true,
  "defaultFlavor": "light",
  "assets": [
    "js",
    "css"
  ],
  "userAssets": {
    "favicon-ico": "images/"
  }
}

In the next section we'll take a look at our theme's flavors.
