I'm trying to optimize one of my pages for iPad. You can see my test-page here: http://demo.dennismadsen.com/ipad/
It contains a black box with a width of 800px. When I see it on my iPad and take a screenshow, I can see, that the box is more when 800px width - about 837px: http://demo.dennismadsen.com/ipad/screenshot.png
I'm wondering why this is happening?
