Go to the My Mibba link at the top of the page. On your right there’ll be a whole bunch of boxes. In one of the it should say CSS. Click it. If you can’t figure out the CSS format(I’m still not 100% sure about how to use it) then there should be a link below the CSS box that says “Use one of our pre-made layouts” or something like that. Click on it and it’ll take you to layouts you can use.
Another way is to go to the forums link and ask someone to make you one. ^^
