@pelmini: The grey box you are concerned about comes from the div at this line. The reason is you have 2 nested control elements each with grid 70-30. Thus the browser creates a Grid of 70% image/control and 30% grey. Inside it puts 70% image and 30% control.
Delete the following div, and your problem will go away!
