Anyone have any ideas on how I can move the blue banner/header up towards the top of the page - as it's displayed in the generic abantecart demo?

I added Google Analytics to the head.tpl and now the blue banner/header at the top of the screen has been moved down and there is a white area above the banner - which doesn't look right.

I deleted the analytics code so the head.tpl was as it was before - however the banner/header is still the same - How do I move it back up to it's original position? (so there is no white area above the blue banner?) Thanks in advance.
