Subject pretty much sums it up. It stretches perfectly in every other browser, of course. :P

Note: PLEASE IGNORE THE MENU ON THE LEFT! I just fixed that and it still doesn't stretch horizontally.



It NEEDS to look like this:



Code:
/* 
main layout
*/

head+body #container:after{
    content: ".";
    display: block;
    height:0;
    clear: both;
    visibility: hidden;
