突然想到以前看到当当上有个效果，当鼠标移上去，图片边框是运动添加上的，还以为是css3或者是canvas做的呢，做完幽灵按钮后，才知道，so easy,只不过是animate+position的杰作。附上代码
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>
*{margin: 0;padding: 0}
div.child{
position: relative;
margin: 100px auto;
width: 200px;
height: 200px;
border: 2px solid #bbb;
box-sizing:border-box;
-webkit-box-sizing:border-box;
background: #ccc;
}
.line{
position: absolute;
display: block;
width: 0;
height: 0;
background: red;
}
.line-top{
/*width: 200px;
height: 2px;*/
left: -2px;
top: -2px;
}
.line-right{
/*width: 2px;
height: 200px;*/
right: -2px;
top: -2px;
}
.line-bottom{
/*width: 200px;
height: 2px;*/
right: -2px;
bottom: -2px;
}
.line-left{
/*width: 2px;
height: 200px;*/
left: -2px;
bottom: -2px;
}
</style>
<script src="js/jquery-1.7.2.js"></script>
<script>
$(function(){
$(‘.child‘).hover(function(){
$(‘.line-top‘).animate({
width: ‘200px‘,
height: ‘2px‘
},1000);
$(‘.line-right‘).animate({
width: ‘2px‘,
height: ‘200px‘
},1000);
$(‘.line-bottom‘).animate({
width: ‘200px‘,
height: ‘2px‘
},1000);
$(‘.line-left‘).animate({
width: ‘2px‘,
height: ‘200px‘
},1000);
},function(){
$(‘.line‘).animate({
width: ‘0px‘,
height: ‘0px‘
},1000);
});
});
</script>
</head>
<body>
<div class="child">
<span class="line line-top"></span>
<span class="line line-right"></span>
<span class="line line-bottom"></span>
<span class="line line-left"></span>
</div>
</body>
</html>
当然，其他的你想要的样式，不妨举一反三做一下，也很简单，只是个运动而已
