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!

The CSS:

<style type="text/css">

a.nowandthen{
position:relative;
display: block;
overflow:hidden;
cursor: pointer;
width: 650px; /* set width of image container */
height: 434px; /* set height of image container */
}

a.nowandthen img{
position:absolute;
left:0;
top:0;
width: 100%;
height: 100%;
-moz-transition: all 0.5s ease; /* enable transition */
-webkit-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
-ms-transition: all 0.5s ease;
transition: all 0.5s ease;
z-index: 2;
clip: rect(0,650px,434px,0); /* clip values should be rect(0,image_width,image_height,0) */
}


a.nowandthen img:nth-of-type(2){ /* hide "after" image beneath "before" so it's initially out of view */
z-index: 1;
}


a.nowandthen:hover img:nth-of-type(1){ /* clip "before" image to reveal "after" */
clip: rect(0,0,434px,0); /* clip values should be rect(0,0,image_height,0) */
opacity: 0;
}

a.nowandthen.alt{
width: 300px; /* set width of image container */
height: 354px; /* set height of image container */
}

a.nowandthen.alt img{
clip: rect(0,300px,354px,0); /* clip values should be rect(0,image_width,image_height,0) */
}

a.nowandthen.alt:hover img:nth-of-type(1){
clip: rect(0,0,354px,0); /* clip values should be rect(0,0,image_height,0) */
}

</style>
