Taper/fade CSS box shadow?

Question

I\'ve got a CSS drop down menu that I\'m trying to build, and the background of the drop down has a faded/tapered box shadow:

Answer 1

1. I've added a before element.
2. gave it a gradient background (from transparent to a semi transparent black) to achieve the top to bottom fade.
3. gave it an inset box shadow to achieve the in -> outfade.

Edit the amount of fade/colors as you want.
