<style type="text/css">
body{ margin:0; padding:0; font-size:30px; color:#fff}
.top{background:#ccc;width:100%;}
.main{background:red;position:relative;overflow:hidden;}
.left{background:blue;width:200px;height:300px;float:left;top:o;}
.right{background:#9C9;height:300px;margin:0 0 0 210px;}
.foot{background:#F63;width:100%;}
</style>
</head>
<body>
<div class="top">top</div>
<div class="main">
<div class="right">right</div>
<div class="left">left</div>
</div>
<div class="foot">foot</div>
</body>
</html>
在不调换left和right的上下位置的情况下，可以让left和right的方块在同一行显示吗？
