以下代码实现一个大的div id=content包含两个左右结构的div，id=side和id= main 并居中放置。并对每个div设计了css样式。
复制代码代码如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<style type="text/css">
#side {
background-color: #00CC66;
float: left;
height: 300px;
width: 120px;
}
#main {
background-color: #CC6633;
height: 300px;
width: 70px;
margin-left:122px;
}
#content {
width: 470px;
margin-right: auto;
margin-left: auto;
}
</style>
</head>
<body>
<div id="content">
<div id="side">此处显示 id "layout" 的内容</div>
<div id ="main">cichu</div>
</div>
</body>
</html>
