一、最大宽度Max Width
<link rel="stylesheet" media="screen and (min-width:900px)" href="big.css" type="text/css" />
表示:当屏幕大于或等于900px时,将采用big.css样式来渲染Web页面。
二、多个Media Queries使用
<link rel="stylesheet" media="screen and (min-width:600px) and (max-width:900px)" href="style.css" type="text/css" />
表示:当屏幕在600px-900px之间时采用style.css样式来渲染web页面。
三、设备屏幕的输出宽度Device Width
<link rel="stylesheet" media="screen and (max-device-width: 480px)" href="iphone.css" type="text/css" />
表示:iphone.css样式适用于最大设备宽度为480px,比如说iPhone上的显示,这里的max-device-width所指的是设备的实际分辨率,也就是指可视面积分辨率
四、not关键字
<link rel="stylesheet" media="not print and (max-width: 1200px)" href="print.css" type="text/css" />
表示:not关键字是用来排除某种制定的媒体类型,换句话来说就是用于排除符合表达式的设备。
五、only关键字
<link rel="stylesheet" media="only screen and (max-device-width:240px)" href="android240.css" type="text/css" />
六、其他
<link rel="stylesheet" media="(min-width: 701px) and (max-width: 900px)" href="medium.css" type="text/css" />
表示:在Media Query中如果没有明确指定Media Type,那么其默认为all
<link rel="stylesheet" type="text/css" href="style.css" media="handheld and (max-width:480px), screen and (min-width:960px)" />
表示:另外还有使用逗号(,)被用来表示并列或者表示或, style.css样式被用在宽度小于或等于480px的手持设备上,或者被用于屏幕宽度大于或等于960px的设备上。
