The 2i2c documentation theme#

A lightweight theme built on the Sphinx Book Theme, for use by 2i2c. It makes minimal changes to the sphinx-book-theme in order to standardize a top-bar that can be shared across all 2i2c documentation.

It does these two primary things:

  • Overrides the layout.html template so that we include a topbar of links and a standard footer.

  • Adds some CSS that standardizes the look and feel according to 2i2c colors

Other than this, the theme behaves the exact same as the sphinx book theme.

Theme build system#

This theme uses the sphinx-theme-builder tool, which is a helper tool for automatically compiling Sphinx theme assets. This will download a local copy of NodeJS and build the theme’s assets with the environment specified in package.json.

Theme structure#

This theme follows the sphinx-theme-builder filesystem layout.

Use this theme in a repository#

To use this theme in the repository, follow these steps:

  • Add this theme to the pip install requirements of the repo. For now, point it to the main branch like so:

    # in requirements.txt

    or to install locally

    $ pip install git+
  • Configure the Sphinx docs to use the theme by editing

    html_theme = "sphinx_2i2c_theme"
  • Make any customizations that you wish, following the sphinx book theme documenation.

Build the theme locally#

You can build the documentation for this theme to preview it. The easiest way to build the documentation in this repository is to use the nox automation tool, a tool for quickly building environments and running commands within them. This ensures that your environment has all the dependencies needed to build the documentation.

To do so, follow these steps:

  1. Install nox

    $ pip install nox
  2. Build the documentation:

    $ nox -s docs

This should create a local environment in a .nox folder, build the documentation (as specified in the configuration), and the output will be in docs/_build/html.

To build live documentation that updates when you update local files, run the following command:

$ nox -s docs-live
