This page demonstrates how to apply the CSS3 box-shadow style.
Use the input controls to specify the background color of the box in the
Preview window. You can then apply a box shadow by specifying whether to
place the shadow outside the box (default) or within (inset) and setting
shadow color, offset in the horizontal and vertical direction, blurring
size, and shadow spread. All distances are expressed in pixels.
Press the Tab key to update the appearance
of the text shadow in the Preview box.
The corresponding CSS3 style rule is displayed in the Style box.
Note that Internet Explorer prior to Version 9 does not support the box-shadow style.
