双飞翼布局和圣杯布局其实是一样的，只不过在写法上有些不同，其布局都是左右固定宽度，中间宽度自适应。
圣杯布局
html结构
<div class="article"> <div class="center">center</div> <div class="left">left</div> <div class="right">right</div></div>
css
先写出大概的样式
.article{ height: 300px; padding: 0 200px;
}.article .left{ width: 200px; height: 100px; background: blue; float: left;
}.article .right{ width: 200px; background: #ccc; height: 100px; float: right;
}.article .center{ background: yellow; width: 100%; height: 100%; float: left;
}现在的布局是这样的

在.left中添加
margin-left: -100%;
在.right中添加
margin-left: -200px;
布局就变成了

最后，在.left中添加
position: relative; left: -100%;
在.right中添加
position: relative; right: -200px;
大功告成

双飞翼布局是在圣杯布局基础上改的
html结构改成了
<div class="article"> <div class="center"><div class="inner">center</div></div> <div class="left">left</div> <div class="right">right</div></div>
css结构改成了
.article{ height: 300px; overflow: hidden;
}.article .left{ width: 200px; height: 100px; background: blue; float: left; /*position: relative;
left: -200px;*/
margin-left: -100%;
}.article .right{ width: 200px; background: #ccc; height: 100px; float: left; /*position: relative;
right: -200px;*/
margin-left: -200px;
}.article .center{ background: yellow; width: 100%; height: 100%; float: left;
}.center .inner{ margin-left: 200px; margin-right: 200px;
}页面是这样的

因为高度不一样所以会显得很难看，要想不固定高度，加上以下代码
.center,.left,.right{ padding-bottom: 9999px; margin-bottom: -9999px;
}大功告成
