A little collection of my own userstyles, probably most of them catppuccin themes
You can either install them via userstyles.world or here (by going to the raw file of a userstyle), although userstyles.world is updated more frequently (like a lot, there may even be new userstyles that I did not yet backup here), GitHub only serves as a backup and platform for contributions.
If you wanna contribute / fix something small etc., please take the current style from the userstyles, and not here, as this is outdated most of the time.
For a quick setup check out my blog.
You can find more catppuccin themes at their official site.

You'll have to enable dark mode in the settings for this to look good.
Contributions are welcome, just open a PR :)
