Centering or stretching Categories Tabs

Ideally, I'd like to be able to have the tabs to stretch to fit the whole page. Yes, I'm a dreamer. Next best thing would be to center the tabs on the page. I found a page that explains how to center the tabs, but I can't figure outhow to apply it to Categories Tabs. Here's the link. Can anyone explain how to apply this to Categories Tabs?

Thanks,
Steve

... uh, I thought we had the category tabs centered already. Did you miss a piece of the stylesheet?

I don't think so. The tabs aligned left right out of the box. Another sitre that uses category tabs, http://www.wittymom.com/store, seems to have the same problem.

Hhhmmm - they look centered to me in a stock install with the Classic template.

I'm sorry, I should have used the full name of the contribution. I'm refering to the Categories Tabs Rollover Style contribution that provides a tabbed appearance.
