Sphinx RTD Theme Dark Mode

This Sphinx extension adds a toggleable dark mode to the Read the Docs theme. A little icon is added in the bottom right hand corner which allows the user to switch between light or dark mode.

Installation

Python 3.4 or higher is required

To install dark mode for the RTD theme, enter the following command into your terminal or command prompt.

# Linux/OSX
python3 -m pip install sphinx-rtd-dark-mode

# Windows
py -3 -m pip install sphinx-rtd-dark-mode

Using the Extension

To use the extension, you will need to add it to the extensions array in your config file (conf.py).

extensions = ["sphinx_rtd_dark_mode"]

You will also need to be using the Sphinx RTD theme for this to work. If your not, then the extension will change it for you as it only works for that theme.

Config

Below are the options that are customizeable for the extension. Currently, there is only one option available to configure.

Default Dark Mode

This lets you choose which theme the user sees when they load the docs for the first time ever. After the first time however, this setting has no effect as the users preference is stored in local storage within their browser. This option accepts a boolean for the value. If this option is true (the default option), users will start in dark mode when first visiting the site. If this option is false, users will start in light mode when they first visit the site.

# user starts in dark mode
default_dark_mode = True

# user starts in light mode
default_dark_mode = False
