The package itself provides an utility function to get the absolute path of
the theme's directory. So, you can put this simple snippet in your
import lightndark_sphinx_theme html_theme_path = [lightndark_sphinx_theme.themes_path()] html_theme = "lightndark"
You don't need to provide a Pygments style, because the whole highlightling thing is handled by the theme itself.
It's recommended to customize the theme when you use it, because even changing the titles' font and links' color will give to your documentation an unique feel.
The easiest way to customize it is to create a theme which inherits from the main one, and changing the options::
[theme] inherit = lightndark [options] accent_color = #004dc2 night_accent_color = #5c9dff titles_font = Courier
Then you can put in your stylesheet other customizations you want to apply, and the code to import the font you want to use for the titles.
Here there is a list of all the available theme options:
accent_color: the main color used by the theme, for links and keywords in the code boxes
night_accent_color: the same as
accent_color, but used in the night (dark) mode
titles_font: name of the font used in titles and headings
