Centering a Spry Tabbed Panels Widget

Hi All,
I’ve been experimenting with the Spry Tabbed Panels Widget to produce a navigation system for a site. It works pretty well except for my inability to center the main Div container.

If you look at the attached link you’ll see that the top row of the navbar is offset to the left. I’ve successfully manipulated the Spry CSS to produce the display I need, colours, fonts etc, but have been unable to have any effect on the centering. Should I be looking at changing the controlling Javascript? Can anyone advise please?
