Hello. Options

Okay, I've gotten a bunch of different codes from different sites, annnnnnd my Xanga looks really neat now.

But I've got some problems?
Whenever I use the CSS codes to change bolded, underlined, and italicized words it doesn't work.
And when I actually go in and put in HTML into the entry, my codes don't work for it - it just goes back to default, but only for the part that I put in the HTML for. Actually, it only doesn't work when I go and do an UL or OL. Actually, it just doesn't work at all for ULs or OLs.

Anyone know why that is? For either?
