Thumbnails of photos is very common part of any website. We have seen a lot of innovation and beautiful representation of thumbnails. Recently I came across a beautiful hover effect on thumbnails. Without saying much first see what is this effect.

The Implementation of this effect is given in the following sections.

The HTML

<div class="thumbnail-wrap">
<div class="thumbnail-div">
<div style="background-image: url(5_thumb.jpg);">
   <img class="thumbnail-shadow" src="thumbnail-shadow.png" alt="bottom" />
<div class="sections-overlay">
    <a rel="imagezoom" href="5.jpg">
     <img class="zoom" src="zoom.png" alt="Some Title of the Image 5" />
    </a>
    <a class="readmore" href="#">read more &gt;&gt;</a></div>
</div>
</div>
</div>


I think the code here is self explanatory.

The CSS

The CSS for the effect is a bit lengthy, as lots of hidden elements are involved.

.thumbnail-wrap {
	float:left;
	height:151px;
	margin:30px;
	width:151px;
}
.thumbnail-div {
	background-color:#313131;
	float:left;
	height:146px;
	padding:5px 0 0 5px;
	width:146px;
}
.thumbnail-shadow {
	float:left;
	height:33px;
	width:100%;
}
.thumbnail-div .sections-overlay {
	-moz-background-clip:border;
	-moz-background-inline-policy:continuous;
	-moz-background-origin:padding;
	background:transparent url(thumbnail-overlay.png) no-repeat scroll -40px -300px;
	float:left;
	margin-top:-33px;
}
.thumbnail-div div{
	height:141px;
	width:141px;
}
.sections-overlay {
	background-image:url(readmore-bg.png);
	opacity: 0;
	visibility:hidden;
	background-position: 0px -167px;
}
.thumbnail-div .sections-overlay .zoom {
	margin:60px 0 0 61px;
}
.sections-overlay .zoom {
	border:medium none;
	margin:165px 0 0 312px;
}
.readmore {
	background-image:url(readmore-bg.png);
	color:#FFFFFF;
	display:block;
	float:right;
	font-size:10px;
	margin:17px 0 0 40px;
	padding:5px 10px;
}

The Javascript : Mootools

And Finally the magic of Mootools to get the desired effect. All this effect is doing to decrease the margin-top of "thumbnail-div" by 10px and showing "sections-overlay" div using opacity:1.

$$('div.thumbnail-div').each(function(div){
  div.addEvents({
    'mouseover': function(){
      $(this).tween('marginTop', '-10px');
      $(this).getElements('div.sections-overlay').each(function(d){
        d.morph({opacity: 1, backgroundPosition: "-40px 0px"});
      });
    },
    'mouseout': function(){
      $(this).tween('marginTop', '0px');
      $(this).getElements('div.sections-overlay').each(function(d){
        d.morph({opacity: 0, backgroundPosition: "0px -167px"});
      });
    }
  });
});
Doing just this we'll get such an amazing effect on Thumbnails. This effect is just a demo of the possibilities. One can use the same technique to show the Title of the Image or RunTime and Title of Video Thumbnail.
