首先写一个index.html文件：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width = device-width,initial-scale=1"/>
<title>响应式布局实例</title>
</head>
<link rel="stylesheet" href="css/style.css" />
<body>
<div class="heading"></div>
<div class="container">
<div class="left"></div>
<div class="main"></div>
<div class="right"></div>
</div>
<div class="footing"></div>
</body>
</html>
其中<meta name="viewport" content="width = device-width,initial-scale=1"/>这句话必须要有，这是获取屏幕分辨率的方法；
然后我们写css自适应：
* {
margin: 0px;
padding: 0px;
}
html {
background-color: beige;
}
.heading,
.container,
.footing {
margin: 10px auto;
}
.heading {
height: 100px;
background-color: coral;
}
.left,
.right,
.main {
background-color: aquamarine;
}
.footing {
height: 100px;
background-color: #FF7F50;
}
@media only screen and (min-width: 960px) {
.heading,
.container,
.footing {
width: 960px;
}
.left,
.main,
.right {
float: left;
height: 500px;
}
.left,
.right {
width: 200px;
}
.main {
margin-left: 5px;
margin-right: 5px;
width: 550px;
}
.container {
height: 500px;
}
}
@media only screen and (min-width: 600px) and (max-width: 960px) {
.heading,
.container,
.footing {
width: 600px;
}
.left,
.main {
float: left;
height: 400px;
}
.right {
display: none;
}
.left {
width: 160px;
}
.main {
width: 435px;
margin-left: 5px;
}
.container {
height: 400px;
}
}
@media only screen and (max-width: 600px) {
.heading,
.container,
.footing {
width: 400px;
}
.left,
.right {
width: 400px;
height: 100px;
}
.main{
margin-top: 10px;
width: 400px;
height: 200px;
}
.right{
margin-top: 10px;
}
.container{
height: 420px;
}
}
在这里我分了3种情况 大于960PX，大于600PX小于960PX，和小于600PX ；
@media only screen and (max-width: 600px) 的写法你学会了么？
