这样的css代码要实现两栏布局为什么网页是空白页？
<html lang="en">
<head>
<meta charset="UTF-8">
<title>document</title>
<link rel="stylesheet" type="text/css" href="lesson6.css">
</head>
<body>
<div class="right"></div>
<div class="left"></div>
</body>
</html>
*{
margin:0;
padding:0;
}
.right{
position: absolute;
right: 0;
width: 100px;
height: 100px;
background-color: #fcc;
opacity: 0.5;
}
.left{
margin-right: 100px;
height: 100px;
background-color: #123;
}
