先了解圣杯布局
雙飛翼與圣杯細微區別
- 雙飛翼比圣杯多了一個內嵌的main-inner標簽
- 雙飛翼設置main-inner標簽magin屬性，內容由maigin撐開。就不用盒子相對定位
實現步驟
1. HTML結構
<div class="container clearfix">
<div class="main">
<div class="main-inner">main</div> //相比較圣杯布局對出來的內容盒子
</div>
<div class="left">left</div>
<div class="right">right</div>
</div>
2. 同圣杯布局類似先給main寬度100%
3. 三個盒子左浮動
4.left盒子margin-left:-100%; right盒子margin-left:-200px(right盒子自身的寬度)
這幾步與圣杯布局基本一致
5. 給內容盒子一個
.main-inner {
margin-left:200px;
margin-right: 200px;
}
完整代碼
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>雙飛翼布局</title>
<style type="text/css">
header,footer {
height: 10vh;
width: 100%;
background-color: #ccc;
}
.clearfix:after {
display:table;
height: 0;
content:"";
clear: both;
}
.container > div {
height: 10vh;
}
.main {
width: 100%;
background-color: #DB5ACF;
}
.main-inner {
}
.left {
width: 200px;
background-color: #9FE444;
}
.right {
width: 200px;
background-color: #39A3CF;
}
</style>
</head>
<body>
<header>header</header>
<div class="container clearfix">
<div class="main">
<div class="main-inner">main</div>
</div>
<div class="left">left</div>
<div class="right">right</div>
</div>
<footer>footer</footer>
</body>
</html>
每天都努力一點點
