Using your own theme assets

You can upload assets, such as images and files, to any of your Help Center themes.

Uploading an asset for your theme

You can upload assets such as images and files to the Help Center. The assets are stored in a web cache in a cloud delivery network (CDN). Web caches reduce bandwidth requirements and server load, and improve response times.

There are a number of allowable file types for themes (see Allowable file types for theme assets).

To upload your own theme assets

1. In Guide, click the Customize design icon () in the sidebar.

2. Click Customize on the theme you want to edit.

3. Click Edit code.

   

4. In the Assets section, click Add asset, then browse to select your file.

   

   Theme asset names must be unique and cannot be more than 50 characters. Asset names can contain any of the following: letters, numbers, dot, minus, plus, underscore, and dash. Asset names are not case sensitive, so you cannot have an asset named asset.jpg and Asset.jpg.

   The asset file is added to your list of asset files.

Allowable file types for theme assets

The following table shows the file types that are allowed as theme assets. The allowable files types for assets are limited to the file types used in the theming of a Help Center.

Asset type	File types allowed
Images	jpg, jpeg, png, gif, svg, webp, tiff, tif, bmp, ico, webm
Fonts	woff2, woff, eot, otf, ttf, svg
Text files	js, css, html, json, txt, xml
Other	mp4, swf, wav, ogg. mp3

Rich content files types, such as Microsoft PowerPoint, Microsoft Word and PDFs, can be article attachments but cannot be theme assets.

Using uploaded assets in the theme’s code

You can reference an uploaded asset in the theme’s style.css file or in its templates. In style.css, you use asset path variables provided by Guide. In templates, you use the Curlybars asset helper.

Using asset variables and helpers in your code lets you easily replace the assets in the theme without editing the theme code. See Replacing an asset in your theme.

You can’t use the path variables or the helper in the theme’s script.js file.

To use an uploaded asset in your theme code

1. In Guide, click the Customize design icon () in the sidebar.

2. Click Customize on the theme you want to edit.

3. Click Edit code.

4. In the Assets section, click the asset file you want to use.

   Various expressions for the asset appear:

   

5. Click Copy to copy the asset expression you need in the Clipboard.
6. Paste the asset expression in your theme code.

Examples

style.css

.class-name {
  background: url($assets-backpack2-jpeg);
}

The value assets-backpack2-jpeg is a variable that contains the relative path to the asset.

.hbs files

In html markup:

<img src="{{asset 'backpack2.jpeg'}}">

In a style tag:

<style>
  .class-name {
    background: url("{{asset 'backpack2.jpeg'}}");
  }
</style>

In a script tag:

<script>
  var assetsBackpack2 = "{{asset 'backpack2.jpeg'}}";
</script>

While you can insert the asset helper in a script tag in a template, you can’t use it in the script.js file.

For more information on editing your theme code, see Customizing your Help Center theme.

Replacing an asset in your theme

Using asset variables and helpers as described in Using uploaded assets in the theme’s code above lets you replace an asset in the theme dynamically without editing the theme code. You can update the theme just by selecting a new asset file on your system.

To replace an asset

1. In Guide, click the Customize design icon () in the sidebar.

2. Click Customize on the theme you want to edit.

3. Click Edit code.

4. In the Assets section, click the asset file you want to replace.

5. Click the options menu on the upper-right side, then select Replace.

   

6. Select a new asset on your system.

   Once uploaded, the theme is updated dynamically by any variable or helper that references the asset. The change is immediate.

   The asset is not replaced if you used the full URL of the asset in the HTML source of published Help Center pages. The link to the asset will break because replacing an asset changes the asset’s published URL. As a result, avoid using the published asset URL in a theme, a page template, or an external web page.

Deleting a theme asset

You can easily delete any theme asset you’re no longer using in your theme.

To delete a theme asset

1. In Guide, click the Customize design icon () in the sidebar.

2. Click Customize on the theme you want to edit.

3. Click Edit code.

   

4. In the Assets section, click the asset file you want to delete.

5. Click the options menu on the upper-right side, then select Delete asset.

   

6. Confirm that you want to delete the asset.

   The asset is removed from your assets list.
