How to make header wider than forum body?

[gopherhockey]

I am wondering how to get a border around the outside of the forums area (just below the header). My vb3 had this, but I can't seem to figure out how to get this back. The "main table width" used to do what I needed, but this is no longer a setting or option that I can locate.

I'm guessing I'd have to do something around the body_wrapper?

Has anyone actually documented what each stylevar is for to make it easier to figure all this out?

Seems to be this, set in the body_wrapper:

margin-left: 10pt;
margin-right: 10pt;
