Theres already a great light colored premade custom css out there if you dont mind most of your site white and light grey. Personally, i usually use subeta at night, and it blinds me.
For others, i have taken this tweakable css and tweaked it a lot more, and came up with something for people that prefer a darker color palette. Pretty much everything is black and grey, with an accent color. It supports facebook cover photos (or banners 315px in height) In this preview image i have my accent color as a dark red and my banner image is my chemical romance. Feel free to change, i have the code labeled where to change the color at and where to stick your new banner.
note: im not a coding wizard. If it looks weird on your screen i probably dont know how to fix it. Also, i only tested it on my laptop. IDK how this will look for everyone else... but since the base code i used HAS been tested on stuff it probably looks fine! :)
okay anyways here is the code im using right now complete with ad blocking and other random tweaks [spoiler=Dark Layout Plus Tweaks] >span[style] { border: 20px solid red; position:absolute !important; left: 50px !important; top: 50px !important; z-index: 1; }
