Fonts and FontAwesome#

The theme includes the FontAwesome 6 Free icon font (the .fa, .far, .fas styles, which are used for icon links and admonitions). This is the only vendored font, and otherwise the theme by default relies on available system fonts for normal body text and headers.

The default body and header fonts can be changed as follows:

  • Using Custom CSS Stylesheets, you can specify which fonts to use for body, header and monospace text. For example, the following can be added to a custom css file:

    :root {
        --pst-font-family-base: Verdana, var(--pst-font-family-base-system);
        --pst-font-family-heading: Cambria, Georgia, Times, var(--pst-font-family-base-system);
        --pst-font-family-monospace: Courier, var(--pst-font-family-monospace-system);
    }
    

    The *-system variables are available to use as fallback to the default fonts.

  • If the font you want to specify in the section above is not generally available by default, you will additionally need to ensure the font is loaded. For example, you could download and vendor the font in the _static directory of your Sphinx site, and then update the base template to load the font resources:

    • Configure the template_path in your conf.py

    • Create a custom layout.html Jinja2 template which overloads the fonts block (example for loading the Lato font that is included in the _static/vendor directory):

      {% extends "pydata_sphinx_theme/layout.html" %}
      
      {% block fonts %}
        <!-- add `style` or `link` tags with your CSS `@font-face` declarations here -->
        <!-- ... and optionally preload the `woff2` for snappier page loads -->
        <link rel="stylesheet" href="{{ pathto('_static/vendor/lato_latin-ext/1.44.1/index.css', 1) }}">
      
      {% endblock %}
      

      Your text may quickly show up as “unstyled” before the fonts are loaded. To reduce this, you may wish to explore options for preloading content, specifically the binary font files. This ensures the files will be loaded before the CSS is parsed, but should be used with care.
