anyway, the best suggestion i'll give is to pick a premade layout and play around with the settings
which you can do by right clicking ANY section of yr page
choosing "inspect element" or whatever
and you'll see the raw css and values such as color, width, font size etc.
you won't make any changes to your profile that way (it's just editing in browser) but...
you CAN copy/paste stuff directly between yr layout's <style> </style> tags
more on this here if you wanna have a read :3
