        </head>
    <body>
<style type=text/css>
/*当浏览器尺寸小于960px时候的代码：*/
@media screen and (max-width:960px){
    body{
        background:green;
    }
}
/*当浏览器尺寸等于960px时候的代码：*/
@media screen and (max-device-width:960px){
    body{
        background:red;
    }
}
/*当浏览器尺寸大于960px时候的代码：*/
@media screen and (min-width:960px){
    body{
        background:blue;
    }
}
/*混合使用上面的用法：
@media screen and (min-width:960px) and (max-width:1200px){
    body{
        background:yellow;
    }
}*/
