I know HTML well, but not CSS, JavaScript, or any of those commodities. I really want to make my own skin, but I don't know how to without those.

Is there any way I can extract someone else's code specifically for the Header and Website Stats sections, so I can figure out how to customize it?

A lot of the information when you view the source Xanga already does, so I don't know what to put in my Look and Feel page and what not to.
