Such a task: to make a div with an inner shadow only at two edges: the top and bottom. In this case, there should be no shadows on the left and right.
Now I have done this like this : one div is 25px out of the window, the other prevents the body from stretching, hiding the rest of the first one.

You can do this:
box-shadow: inset 0 15px 15px -15px # 333, inset 0 -15px 15px -15px # 333;
The shadow will only be above and below. You can watch it here: http://jsfiddle.net/shpQ4/2/
Only tested in IE 10, but I think it works in all major browsers.
