Thanks for the feedback! This demo isn't intended to be functional (clicking the tabs won't do anything, that requires JavaScript code which is out of scope for this demo), it's just there to show an example of how you could style things using CSS3.
I can verify there is a bug in IE8 where there is an extra gray line at the bottom of the active tab. I will attempt to fix that ASAP. It works properly in IE6 and IE7.
