二：两列布局-自适应
来源：http://www.cnblogs.com/catball/
<style>
.left { width:180px; float:left }
.right{ margin:0 0 0 180px;border:1px solid #ff0000;}
</style>
<div class='left'>撒地方十克拉的发多少</div>
<div class='right'>是大方家萨附近多少
<br/>
<br/>
<br/>
<br/>
<br/>
<br/> <br/> <br/> <br/> <br/> <br/>
</div>
简单的把right的 左边距设为left的宽度即可
2.<style type="text/css">
<!--
#left {
float:left;
width:200px;
height:100px;
background:#f00;
}
#right {
float:left;
width:200px;
height:100px;
background:#fc0;
}
-->
</style>
</head>
<body>
<div id="left">YourHomePage.com.cn</div>
<div id="right">YourHomePage.com.cn</div>
</body>
(三)style.top 与style.left
在IE中可以直接用obj.style.top=100;但在FireFox中必须加上单位，变成obj.style.top=100+'px';
style.left同理。
