A Shadow Demo
An idea I got late one night. To have a shadowed div that was absolutely positioned in the center of the page. The design is simple, 3 divs, all absolutely positioned, with negative margins on the innermost, or content div. May be useful for pages with small amounts of text or links.
You may choose to use negative absolute positioning on the content div—the results are the same. It's important to set the overflow property to auto on the content div to prevent the design from breaking when text is resized.
