jQuery sliding boxes and captions to create callouts

The concept behind the sliding boxes and captions is pretty easy. Check out the demo below to see what’s going on. There is a div with a border and shadow which contains an image. On top of the image there is a div (the caption) which has a background color, a border, some text, links, and other elements with background images. The opacity has been lowered on the background color so the image can shine through the div.
