User blog:Hax4Ever/Anybody have some good CSS code that I can use for my wiki?

Hello there!

I'm trying to make my wiki look cool and professional but I'm running into alot of problems

Alot of the CSS I found on this wiki has "!Important" On it, And It doesn't know what it's use is.

And plus I want some css to make my wiki look fancy, Like The Header on this wiki m How would I get something like that?

I have no skill in CSS whatsoever so It will really help if everyone can show me some good ones.
