双飞翼(圣杯布局)
1利用定位实现两侧固定中间自适应
-
父盒子分支左右padding值
-
给左右盒子的width设置父盒子的padding值然后分别定位到padding出
-
中间盒子自适应

.box {
position: relative;
width: 500px;
height: 50px;
background-color: aqua;
margin: 100px auto;
}
.box1 {
position: absolute;
left: 0;
top: 0;
width: 50px;
height: 50px;
background-color: bisque;
}
.box3 {
position: absolute;
right: 0;
top: 0;
width: 50px;
height: 50px;
background-color: bisque;
}
</style>

<body>
<div class="box">
<div class="box1"></div>
<div class="box2"></div>
<div class="box3"></div>
</div>
</body>
</html>
2:使用弹性布局display:flex
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<style>
* {
margin: 0;
padding: 0;
}
.box {
display: flex;
width: 40%;
height: 50px;
background-color: aqua;
margin: 100px auto;
}
.box1,
.box3 {
width: 50px;
height: 50px;
background-color: red;
}
.box2 {
flex: 1;
background-color: black;
margin: 0 10px;
}
</style>
</head>
<body>
<div class="box">
<div class="box1"></div>
<div class="box2"></div>
<div class="box3"></div>
</div>
</body>
</html>
通过这两种方法都可以实现圣杯布局但是相比较display:flex弹性布局更简洁一点这点比较实用,不过因人而异看自己喜好去实现去完成就行啦
