div问题。速度回答下呵呵
<style type="text/css">
#head { margin:5px 500px auto;width:1000px; height:300px; background:#9FF;}
#main { margin:5px 800px auto;width:700px; height:300px; background:#9FF;}
#tail { margin:5px 800px auto;width:700px; height:300px; background:#9FF;}
#left{ margin:5px 500px auto;width:300px; height:700px; background:#9FF;}
</style>
<body>
<div id="head">aaaa</div>
<div id="main">bbbb</div>
<div id="left">dddd</div>
<div id="tail">cccc</div>
这段代码中如何让bbbb与dddd平排(如果不知道平排啥意思可以这样理解。bbbb在右上角，dddd在左上角)
