div 边框阴影本篇文章是讲关于css 边框阴影效果代码，我们讲了两种实现方法一种是利用内外层的div边框来实例层次感觉的css边框阴影效果，另一种是利用了背景图片再加内外div来实现的这种效果更漂亮。
简单一点的纯css
<head>
<meta http-equiv=”content-type” content=”text/html; charset=gb2312″ />
<title>css div 边框阴影</title>
<style type=”text/css”>
body {padding: 200px;}
div {border-width: 1px; border-style: solid; padding: 1px;}
.a {background-color: #f3f3f3; border-color: #fbfbfb;}
.b {background-color: #d8d8d8; border-color: #e8e8e8;}
.c {background-color: #fff; border-color: #bbb; height: 100px;color：#ff0000;}
</style>
</head>
<body>
<div class=”a”>
<div class=”b”>
<div class=”c”>边框为阴影效果</div>
</div>
</div>
</body>
</html>
复杂一点的利用图片背景
<!doctype html public “-//w3c//dtd xhtml 1.0 transitional//en” “”>
<html xmlns=””>
<head>
<title>css边框阴影</title>
<style>
.drohadow2{
float:left;
clear:left;
background: url() no-repeat bottom right !important;
background: url() no-repeat bottom right;
margin: 10px 0 10px 10px !important;
margin: 10px 0 10px 5px;
width: 500px;
padding: 0px;
}
.innerbox{
position:relative;
bottom:6px;
right: 6px;
border: 1px solid #999999;
padding:4px;
margin: 0px 0px 0px 0px;
}
.innerbox{
/* ie5 hack */
margin: 0px 0px -3px 0px;
margin: 0px 0px 0px 0px;
}
.innerbox p{
font-size:14px;
margin: 3px;
}
</style>
</head>
<body>
<div class=”dropshadow2″><div class=”innerbox”><h4>css阴影：</h4> <p>这段边框阴影效果怎么样呢？</p></div></div>
</body>
</html>
