This is a demo site for Bootstrap, generated as part of Sphinx Themes Gallery.
This sample documentation was generated on May 16, 2022, and is rebuilt weekly.
Install this theme:
$ pip install sphinx-bootstrap-theme
Set the following in your existing Sphinx documentation’s
import sphinx_bootstrap_theme html_theme = 'bootstrap' html_theme_path = sphinx_bootstrap_theme.get_html_theme_path()
Build your Sphinx documentation with the new theme! 
This theme does not have any hosted-on-the-web documentation.
The Kitchen Sink section contains pages that contains basically everything that you can with Sphinx “out-of-the-box”.
Browsing through that section should give you a good idea of how stuff looks in this theme.
