I was wondering if someone could post some of these things for me because I dont want xanga no more... I want blogger.

Can you post:
A Stylesheet.

A div to move the blog body around.

Something to make custom modules.

And how do I add a background image?

O and I was being bored and moved my xanga code to blogger and it mostly worked... so shouldnt all the codes work?

There's a lot of unneeded uh.. tags in your Xanga css that you can remove because they won't apply to Blogger.
