Something weird is happening in that layout though. Maybe it's just Chrome/Webkit but if you double click anywhere a grid overlays itself onto the page. It seems to be on purpose ( background-image: url(<a href="http://blog.peepcode.com/images/grid/27px-leading-w-60-80-grid.png" rel="nofollow">http://blog.peepcode.com/images/grid/27px-leading-w-60-80-gr...</a>); ) but it seems quite bizarre.
