基本思路:
-
左右2列采用绝对定位来布局
-
中间内容部分采用margin挤压出来
HTML结构
<div class="container">
<div class="left">左侧</div>
<div class="right">右侧</div>
<div class="main">主体</div>
</div>
CSS样式
<style type="text/css">
.container{
position: absolute;
left: 0;
right: 0;
}
.left{
top: 0;
left: 0;
position: absolute;
width: 200px;
height: 600px;
background-color: aqua;
}
.right{
top: 0;
right: 0;
position: absolute;
width: 200px;
height: 600px;
background-color: yellowgreen;
}
.main{
margin-left: 200px;
margin-right: 200px;
height: 600px;
background-color: papayawhip;
}
</style>
