Cool Character [C] CSS

Hey, woah. This isn't right at all. This isn't HTML!
Yeah, actually I'm learning a bit on how to do CSS. I feel like I've (almost) mastered Bootstrap, so where else is there to go? Sorry if it's a little cluttered and messy, this is my first time actually putting together CSS all on my own.
This is CSS, so it requires ToyHouse Premium in order to use! This is strictly for character profiles only, no promises it'll work as well for user profiles or worlds.

Please try to find a way to credit me if possible! Maybe include it in your character's HTML code.
