div header with vb menu dhtml popups?

[waza]

Hey,
I want to make a tabless lay-out, and so I start with the header.
I have put them in <div>'s, css etc, but What to do with the vb popup menus.
Normally we have to do like this: <td id="popupname">, but what with <div>'s?

Btw, I heard about a vbulletin css project, where can I find that?

Grz,
seba
