1. Left fixed, right adaptive
css :float+margin
<head>
<meta charset="utf-8">
<style>
*{
margin:0;
padding:0;
}
.left{
width:200px;
height:300px;

background-color:yellow;
}
</style>
</head>

<!-- Two-column layout -->
<!-- Fixed width on the left, adaptive on the right-->
<div class="left"></div>
<div class="right"></div>
</body>
Here is the effect:
