Dark theme

[rperson1508]

Hello, how do I configure dark mode for sphinx-book-theme?
I have not found any specific way to do so in the documentation.

It does not currently exist, see this GitHub issue for discussion of adding this enhancement:

• Add a dark mode sphinx-book-theme#265

Alright but I thought I saw that it has been merged?

Digged further and found the customizing guide on the docs.

conf.py

html_theme = 'sphinx_book_theme'
html_static_path = ['_static']
html_css_files = [
    'css/custom.css'
]

_static/css/custom.css

/* Dark theme */
html[data-theme="dark"] {
    background: #000000;
}

After re-building the documentation (and refreshed), the background colour did not change. Were there any mistakes I made?
