Before and After (Peel Back) Image
Author: Dynamic Drive
"Before and After" images are always fun to look at, especially if the right transition is used to effectively swap between the two. This CSS example shows just that, using CSS3 animation to animate the "clip" property of the "before" image to peel back and reveal the "after" image onMouseover. The result is a simple but sleek "Before and After" Image effect!
