How to modify the theme

Depending on how much you want to modify the theme, use one of these options.

On this page

Add or override styles

To override or add additional JavaScript and CSS, you don’t need to install the theme’s dependencies.

To add additional CSS files, use the html_css_files configuration value. To add additional JavaScript files, use the html_js_files configuration value.

For example, place additional styles in a file _static/custom.css and add the following options to your Sphinx configuration in conf.py:

python conf.py 
html_static_path = ["_static"]
html_css_files = ["custom.css"]

If you want to override existing styles, you might have to add !important. For more information, see the Mozilla Developer Networks.

Note

Since these additional CSS and JavaScript files aren’t parsed by Webpack, use your own styles and don’t use Tailwind’s @apply directive.

Modify the templates

Styles in the templates are applied via Tailwind’s utility classes.

shell 
./src/
├sphinxawesome_theme/
└theme-src/

To modify these styles, follow these steps:

  1. Install the Python and JavaScript dependencies.

    See Set up a development environment for more information.

  2. Make your change.

    For example, to change the background color of the header to orange, open sphinxawesome_theme/header.html and change:

    html 
    <header class="md:sticky top-0 bg-gray-900 ...">
<header class="md:sticky top-0 bg-orange-500 ...">

  3. Build the theme.

    shell 
    $ yarn build

Modify CSS files

Everything that’s part of the main content, including everything that’s converted from reStructuredText to HTML is styled using Tailwind’s @apply directive.

shell 
./src/
├sphinxawesome_theme/
└theme-src/
 └css/

To modify these styles, follow these steps:

  1. Install the Python and JavaScript dependencies.

    See Set up a development environment for more information.

  2. Make your change.

    The CSS files are arranged according to the elements they apply to. For example, if you want to change the appearance of links from the default blue to an orange, open theme-src/css/links.css and change:

    css 
    p:not(.admonition-title),
.nav-toc,
.search,
.toctree-wrapper,
.contents.local {
  & a {
    @apply text-blue-700;
    @apply text-orange-500;
  }
}

  3. Build the theme.

    shell 
    $ yarn build
