@alicia …That’s Paulie…but no problem.
At the moment the nav ‘box’ just floats up until it hits something but sure, you can mess with the margins to get it exactly where you want.
As for the footer…taking it out of the page wrap div will automagically make it 100% width of the browser window. Obviously I can’t speak for what might be happening in your monitor or with your current code. http://jsfiddle.net/Paulie_D/bMhhn/4/
Just in case, you can always set the width to 100% if you feel the need..
