Ok I guess I solved my problem by adding a <br /> to your header code at the bottom:

                         </ul>
                </div>
        </body>
<br />
</html>

I then had to change the border-bottom code to: border-bottom:2px solid #0B198C;
This matches the default theme perfect which your color code does not.

Now my next question is how do I get the tabs to be aligned next to the right margin rather than the left side?

Secondly, the first left tab seems to be higlighed in a darker blue even when the mouse is not rolled over it. How can that be fixed so it matches the other tabs?
