Increasing width of navigation bar and columns

Hi there Mark,

Firstly great themes there are fantastic. I have question I want to increase the display from the 960 content to the 100% width. However when I do this everything gets out of line and the nav bar and columns dont automatically adjust for the full width. How could I go about increasing the width of the nav bar and buttons, as well as the columns so that they are all aligned on the full width.

I’ve attached a snippet showing the problem.

P.S Im a novice at CSS and wordpress etc so the more detailed the better!

Thanks in advance!
