how do I keep a nav bar at the top of the page?

[Connor891]

I'm trying to make my nav bar stay at the top of the page like on http://www.forbes.comI know I could do\[code\]nav{ position: fixed; top: 0;}\[/code\]but the nav bar isn't at the top of the page, it comes after the logo... When you scroll down however, I want the nav bar to stick to the top of the screen..this is my site http://fusedigital.eu
