The best as you can change the font or background colors, which you cannot do with the other extensions like dark reader.

This extension has an edge over Dark Reader (another extension that darkens sites) in that it allows for not only more customization, but allows for applying it within sub directories of a website (useful for wordpress, to dark theme only the admin panel and not interfere with primary website). No other extension has that and is only all or nothing for a website.

it doesnt work

Great job, man!
