Recently I was visiting my site (byteaspect.com) on an iPad and noticed that the header was cropped. I could recreate the problem on my desktop computer by resizing the window and then scrolling to the right (see image). I've managed to get the ad to display without getting cropped, but the header in its entirety is still cropped.
I've uploaded the css for the header (and then some) to pastebin.com: here
Any help would be awesome!
