图标滑过图片缓缓变明晰，当鼠标分开图片仍然留下残影，点击后缓缓放年夜，其它图片会很灵巧的主动陈列
第一步：
下全副源代码及演示图片

第二步：
正在网页<head>区增加如下代码
[code]
<style type="text/css">
html {
overflow: hidden;
}
body {
margin: 0px;
padding: 0px;
background: #000;
position: absolute;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
}
#screen {
position: absolute;
top: 1%;
left: 1%;
width: 98%;
height: 98%;
background: #000;
color: #fff;
}
#screen div {
position: absolute;
overflow: hidden;
cursor: pointer;
}
#screen img {
position: absolute;
width: 100%;
height: 100%;
}
#screen .label {
position: absolute;
color: #FFF;
background: #000;
font-family: arial;
white-space: no-wrap;
}
</style>
