Has any one made any custom css themes (Stylish) for sitepoint?

Not sure if this is the right section for this to post.
Has any one made any stylish themes for Sitepoint ? ( For those who do not know : You can add your own css to a website using the stylish plug-in on Firefox , I think it works in chrome too). I tried to make some just for fun today but I found it really difficult to understand the css on this site & gave up after coming up till here.
I know it looks terrible, Just wondering if you designer guys have made some ?

Many of us have our own style sheets for this site, but only just simple tweaks rather than a whole new design. Looks like you did pretty well! I’d say you well and truly have your head around this. If you have a specific question, feel free to ask.
