python-furo

Furo is a Sphinx theme, which is:

Intentionally minimal --- the most important thing is the content, not the scaffolding around it.
Responsive --- adapting perfectly to the available screen space, to work on all sorts of devices.
Customizable --- change the color palette, font families, logo and more!
Easy to navigate --- with carefully-designed sidebar navigation and inter-page links.
Good looking content --- through clear typography and well-stylized elements.
Good looking search --- helps readers find what they want quickly.
Biased for smaller docsets --- intended for smaller documentation sets, where presenting the entire hierarchy in the sidebar is not overwhelming.
