you have to purge the cache after making changes to the style.
also, you need to change your common.css you have both maximum and minimum set to 1400 px you need to change the minimum back to 625
the way you have it set now it creates a horizontal scroll even on my 32 inch monitor.
you probably should change the 1400 to something like 1200 or 1250 etc.
