I noticed that you have two curly braces at the end of #secondary. I would also suggest to check the placement of ids primary and secondary in html file and media query syntax. Hope it helps.

There is a couple of things I would look for. 1st, check and see if you added the clearfix to the floated elements in the CSS. 2nd, double check and see if you are using id's or classes in the markup. Sometimes this is the issue. if you can paste some more code into the question it would be easier to look at, and see what is going on. I hope this helps.

Thanx for your input. It's the combination of curly brackets, and the nice id that i'd misspelled.
