High-level description

This code defines a custom layout template for a Sphinx documentation site, inheriting from the pydata_sphinx_theme/layout.html template and overriding the fonts block to specify font families for the body and header elements.

​

Symbols

​

{% extends "pydata_sphinx_theme/layout.html" %}

​

Description

This line instructs the template engine to inherit the base layout from the pydata_sphinx_theme/layout.html file. This means that the current template will use the structure and elements defined in the base template, and only the overridden blocks will be different.

​

{% block fonts %} … {% endblock %}

​

Description

This block overrides the fonts block defined in the base template. It allows customizing the fonts used in the documentation site.

​

Internal Logic

The code within this block defines a <style> tag containing CSS rules for the body and .header-style elements.

• body { font-family: ...; }: This rule sets the font family for the entire body of the documentation pages. It uses a font stack starting with system fonts for better cross-platform consistency and falls back to generic sans-serif fonts.
• .header-style { font-family: ...; }: This rule sets the font family for elements with the class header-style. It uses the same font stack as the body rule.

​

Dependencies

This template depends on the pydata-sphinx-theme package, which provides the base layout template (pydata_sphinx_theme/layout.html).
