更好的方法是分离css文件,更易于维护

<link rel="stylesheet" media="screen and (min-device-width : 320px) and (max-device-width: 480px)" href="iphone.css" /><link rel="stylesheet" media="screen and (min-device-width : 768px) and (max-device-width : 1024px)" href="ipad.css" />

最后不要忘了加上viewport

<meta name="viewport" content="width=device-width, initial-scale=1.0" />
