the attachment shows the most basic form of this problem. it uses a single div with relative positioning with overflow set to hidden, and its clip set to auto. this requires the div to expand to the full content width/height, and theoretically hide any overflow. There is never any overflow when a div expands to its full width/height and so should never hide any content. The clip set to auto ensures that the region to be hidden is at the edge of the content.
