双飞翼布局
双飞翼布局与圣杯布局细微区别
- 双飞翼布局比圣杯布局多了一个 main-inner标签
- 双飞翼布局不需要盒子定位
- 双飞翼布局是由内容main-inner盒子的maigin撑开
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>

- 同圣杯布局类似先给main宽度100%
- 三个盒子左浮动
- left盒子margin-left:-100%; right盒子margin-left:-200px(right盒子自身的宽度)
- 给内容盒子一个margin-left
.container > div {
float: left;
height: 10vh;
}
.main {
width: 100%;
background-color: #DB5ACF;
}
.main-inner {
margin-left:200px;
}
.left {
width: 200px;
background-color: #9FE444;
margin-left: -100%;
}

- 同理给right盒子
.right {
width: 200px;
background-color: #39A3CF;
margin-left: -200px; /* 不能用100% */
}
