I'm working on a set of templates (I'm a designer, not a programmer), and am wondering if there is a neat trick to get the logo graphic to center in the header, rather than having to give it an absolute position. I don't know of an easy way to do this using only the style sheet. I've got everything else looking good, but the graphic treatment for the header would sure look a lot better if it could float centered as the page is resized.
Looking on the admin screen under the instances link it shows that the header has an instance of local.samples.HeaderContentPortlet.
It looks like this may be the Portlet you want to extend. Although since I'm a newbie here I could be mistaken.
Any other suggestions?
