Your other scripts have an option "Install directly from github" that works wonderfully with GreaseMonkey/TamperMonkey but I can't seem to install this.
Perhaps because it's a .css and not a .js, I don't know.
Just pasting the code doesn't work either, nor does installing from URL.
Probably know me from my old dark trakt theme (or maybe not) xD but I ended up deprecating my theme as I just never have time to really do a whole lot with it anymore and started pointing people toward your theme in my repository (along with myself using your theme now as well).
Anyways I ran into a few small bugs so far that I'd just thought I'd point out, and this is mainly to due with the dev branch as that is the branch I am testing with mainly (though I will mention if it's broken in the master branch as well or not).
(Dev only)
Shows pages are still completely white, dunno if you have gotten around to the show page side of things yet or not in the dev branch but it works fine in the master branch.
(Dev and Master)
Both highlighted and quote blocks are completely white, with white text. Highlighted is more of a yellow tint but the text is still completely unreadable.
(Dev Only)
Discover page comments section is white as well.
(Dev Only)
Liked/Faved List page for users, has a block of white background on both sides of the screen going all the way down, and descriptions that have the "read more" have a white shade to them.
(Dev and Master)
The search bar upon opening is white as well (dev branch), on the master branch it flickers white when opening and then shortly after goes dark.
Just a couple of the things I've noticed so far, if I find anymore I will write them down.
Edit: oh also, on dev branch the "ratings-on-trakt" userscript is broken as well.
