圣杯布局与双飞翼布局针对的都是三列左右栏固定中间栏边框自适应的网页布局
显示如图：
(1)、浮动布局（float+calc）
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>菜鸟教程(runoob.com)</title>
<style type="text/css">
.container {
width: 100%;
height: 300px;
}
.container > div {
float: left;
}
.left, .right {
width: 60px;
height: 100%;
}
.left {
background-color:red;
}
.right {
background-color:blue;
}
.main {
width: calc(100% - 120px);
height: 100%;
background-color:green;
}
</style>
</head>
<body>
<div class="container">
<div class="left"></div>
<div class="main"></div>
<div class="right"></div>
</div>
</body>
</html>
(2)、绝对布局（absolute+calc）
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>菜鸟教程(runoob.com)</title>
<style>
.container{
width:100%;
height:300px;
position:relative;
}
.container > div{
position:absolute;
height:100%;
}
.left,.right{
width:100px;
}
.left{
left:0;
background-color:green;
}
.right{
right:0;
background-color:blue;
}
.main{
width: calc(100% - 200px);
left:100px;
background-color:red;
}
</style>
</head>
<body>
<div class="container">
<div class="left"></div>
<div class="main"></div>
<div class="right"></div>
</div>
</body>
</html>
(3)、flex布局
<!DOCTYPE html>
