先了解圣杯布局
双飞翼与圣杯细微区别
- 双飞翼比圣杯多了一个内嵌的main-inner标签
- 双飞翼设置main-inner标签magin属性，内容由maigin撑开。就不用盒子相对定位
实现步骤
1. HTML结构
<div class="container clearfix">
<div class="main">
<div class="main-inner">main</div> //相比较圣杯布局对出来的内容盒子
</div>
<div class="left">left</div>
<div class="right">right</div>
</div>
2. 同圣杯布局类似先给main宽度100%
3. 三个盒子左浮动
4.left盒子margin-left:-100%; right盒子margin-left:-200px(right盒子自身的宽度)
这几步与圣杯布局基本一致
5. 给内容盒子一个
.main-inner {
margin-left:200px;
margin-right: 200px;
}
