Hi guys, I'm trying to get to grips with the twenty thirteen theme for wordpress and moving the nav to a vertical position. I think along the lines I've balled something up and now when you shrink the page the main body of the site does not move with the header. Any ideas on how to fix this? Link to site is here.

i guess u have fixed the issue?

Yes thanks Sash. After giving it a break and bringing some fresh eyes to it I managed to see the issue. Cheers
