[SOLVED] Center Header Widget?

Hey guys,

This is how I set up my header area for now, but I'm a little stumped on how to center this widget.

%bar1 %image <?php bfa_widget_area('name= Header Widget'); ?> %pages %bar2

It's an add in the header. It's currently sitting on the left - could you let me know where in the theme options/which theme option... I can make the change so it is centered on my page.

Thanks,
Chris
