More centering

Hi all,

I'm trying to build a fixed-width site which has two copies of the page menu bar - at the top it needs to be justified right due to some graphics, and at the bottom of the page it should be centered. I've noodled around with a bunch of variations on how to do this - the best possibility so far is to use the otherwise unused Category menu bar CSS on the bottom one. But when I try centering, the background color (using the CSS insert described at http://forum.bytesforall.com/showthread.php?t=2548) starts at the first menu item on the left and hangs off past the page border to the right on most browsers.

Any suggestions on how to best take care of this?

Thanks!
