Sphinx

Sphinx uses Pygments for syntax highlighting in code blocks. Pygments is a popular library for code coloring, supporting a wide range of programming languages and styles.

Each Sphinx theme comes with a default Pygments style, which determines how code blocks are rendered.

This means that when you select a theme, it automatically applies its own color scheme to all code examples.

Configuration

If you want to customize the appearance of code blocks, you can override the default Pygments style by specifying your preferred styles in conf.py.

For example:

conf.py

pygments_style = "one-light"
pygments_dark_style = "one-dark-pro"

This allows you to maintain your chosen theme while adapting code highlighting to your personal preferences or to better match your project’s design.
