Hey Jason, thanks for your reply.
This page in particular is a static HTML 5 page with other PHP pages being added later.
I've uploaded the page to a testing server for you to see and can be found here: http://abrasives.whowantsfun.com/index.html
I just had a thought, when I told the CSS builder it to be 320px wide, could that have meant individual buttons or the whole bar?
Thanks.
