Box-shadow

The CSS   property allows users to cast a drop shadow from the frame of almost any arbitrary element. If a  is specified on the element with a box shadow, the box shadow will take on the same rounded corners. The z-ordering of multiple box shadows is the same as multiple s (the first specified shadow is on top).
