box-shadow: horizontal-offset | vertical-offset | blur-distance | spread-of-shadow | color

Horizontal offset:  Negative values position the shadow to the left of the box.
Vertical offset:    Negative values position the shadow to the top of the box.
Blur distance:      If omitted, the shadow is a solid line like a border.
Spread of shadow:   Positive value will cause shadow to expand in all directions, and negative value will make it contract.
