首先是css代码：
<style type="text/css">
<!--
*{margin:0px;padding:0px;border:0px;list-style-type:none; font-size:12px;text-decoration: none;}
.hd{width: 960px;overflow: hidden;background-color: #33CCFF;height: 100px;margin-right: auto;margin-left: auto;}
.bd {width: 960px;overflow: hidden;background-color: #BBCADE;margin-right: auto;margin-left: auto;margin-top: 8px;margin-bottom: 8px;}
.bd .l_pt1 {width: 200px;overflow: hidden;background-color: #663366;float: left;height: 200px;clear: left;}
.bd .l_pt2 {width: 200px;overflow: hidden;background-color: #666;height: 200px;margin-top: 8px;clear: left;float: left;}
.bd .r_pt {background-color: #33CCFF;margin-left:200px;}
.clear {font-size: 0px;clear: both;overflow: hidden;line-height: 0px;height: 0px;}
.ft {width: 960px;overflow: hidden;background-color: #33CCFF;height: 100px;margin-right: auto;margin-left: auto;}
接下来是div：
<div class="hd">此处显示 class "hd" 的内容</div>
<div class="bd">
<div class="l_pt1">fdsf</div>
<div class="l_pt2">fdsafasf</div>
<div class="r_pt">
<p>dsdasdsadasd</p>
</div>
<div class="clear"></div>
</div>
<div class="ft">此处显示 class "hd" 的内容</div>
