Color schemes

Just the Docs supports two color schemes: light (default), and dark.

To enable a color scheme, set the color_scheme parameter in your site’s _config.yml file:


# Color scheme supports "light" (default) and "dark"
color_scheme: dark

Custom schemes

Define a custom scheme

You can add custom schemes. If you want to add a scheme named foo (can be any name) just add a file _sass/color_schemes/foo.scss (replace foo by your scheme name) where you override theme variables to change colors, fonts, spacing, etc.

Available variables are listed in the _variables.scss file.

For example, to change the link color from the purple default to blue, include the following inside your scheme file:


$link-color: $blue-000;

Note: Editing the variables directly in _sass/support/variables.scss is not recommended and can cause other dependencies to fail. Please use scheme files.

Use a custom scheme

To use the custom color scheme, only set the color_scheme parameter in your site’s _config.yml file:

color_scheme: foo

Switchable custom scheme

If you want to be able to change the scheme dynamically, for example via javascript, just add a file assets/css/just-the-docs-foo.scss (replace foo by your scheme name) with the following content:`

{% include css/just-the-docs.scss.liquid color_scheme="foo" %}

This allows you to switch the scheme via the following javascript.


Override and completely custom styles

For styles that aren’t defined as variables, you may want to modify specific CSS classes. Additionally, you may want to add completely custom CSS specific to your content. To do this, put your styles in the file _sass/custom/custom.scss. This will allow for all overrides to be kept in a single file, and for any upstream changes to still be applied.

For example, if you’d like to add your own styles for printing a page, you could add the following styles.


// Print-only styles.
@media print {
  .side-bar, .page-header { display: none; }
  .main-content { max-width: auto; margin: 1em;}
