I'm trying to use the position fixed css on a simple one page website with vertical scrolling but am facing problems with IE9, it's like it's ignoring the fixed property, you can see the website here

looks right on chrome, firefox.
Appreciate the help. Yehia
Try adding a doctype to make sure IE9 isn't going into quirks.
This took me a while to figure out. I was writing some javascript using which contained code to write to console.log. Never noticed it was a problem as i never use IE and nothing appeared to be broken in FF or chrome. I had the js above my declaration and that was what was causing the error. you shouldnt put anything browser side before that declaration.
