UserScripts and UserStyles

These are scripts and styles that allow you to change the way a website looks, if you don't know the difference, I wouldn't worry about it. Just know that userstyles will require an extension called stylus, and userscripts use tampermonkey (you could use like greasemonkey or smth but I prefer tampermonke)

Also, if a link is a file on github and you dont know where to go from there, click on the raw button and it should open in whatever extension the css file uses.

Also also, it is a good idea to read the descriptions of these, as some may not work as intended, require an extension or smth else, be really old, etc.
