Sometimes designs are fixed heights, and as such the content div needs to have its own little scrollbox (rather than the standard sidebar one). I've had a few projects where I've used overflow:auto, basically if the div's content is over XYZpx high, then scrollbars will show up and they can scroll the content (like the box on the demo). This part is wrong: "It is not possible to find a cross-browser way of applying a background image to this scrollable area.". I know that's rubbish because I set a bottom right background image on one just the other week.

This isn't a substitute for an iframe. Iframes get remote pages and loads them in - this doesn't.
