@3NexJan 14.2012 — #Only left and right, without top and bottom? I don't think that's possible with only drop shadow, but it could be faked with two divs instead of one.
Here's a complete guide to shadows, you have some examples near the middle of the document.
@SupplementauthorJan 16.2012 — #So there is still a bit of a problem and you'll see the border on the bottom if you ctrl and make the page as small as can be...
Additionally, you won't see the border on the bottom if you didn't ctrl and make super small... but is there a way to extend just all the way down without seeing that border no matter how small you make the page?
@rtretheweyJan 17.2012 — #If you mean the way the center image of the gadgets bleeds through the right side of your shadowed container, then yes. It's the containing DIV. The class .grid2col sets the width to 100%, but then it seems there's a padding or margin issue with the containing element - presumably a <div> - which bumps it to the right so it overflows. Try removing the .grid2col class and then deal with whatever is bumping things to the right.
