Disappointed with the lack of good dark themes for pdoc, I created my own based on Tokyo Night with a hint of my other favorite theme Moonic. It uses JetBrains Mono for code formatting.

1. Save theme.css and syntax-highlighting.css from the theme folder into a folder of your choosing
2. Run pdoc -t pointing to that folder, using pdoc-tokyo-night as an example:

pdoc -t pdoc-tokyo-night $PKG_NAME

I hope it helps brighten darken up your documentation. Enjoy!
