文字
语法：
@media：<media_query_list>
<media_query_list>：[<media_query>[',' <media_query>]*]?
<media_query>：[only | not]? <media_type> [and <expression>]* | <expression> [and <expression>]*
<expression>：'('<media_feature>[:<value>]?')'
取值：
<media_type>：指定设备类型。媒体类型包括：参阅媒体类型。(CSS2)
<expression>：指定媒体查询使用的媒体特性。这类似于CSS属性，如：max-width:960px。(CSS3)
说明：
指定样式表规则用于指定的媒体类型和查询条件。
IE8及以下只能实现CSS2中的部分，即只可以设置媒体类型。
媒体查询可以被用在CSS中的@media和@import规则上，也可以被用在HTML和XML中。
示例代码：
@media screen and (width:800px){ … } @import url(example.css) screen and (width:800px); <link media="screen and (width:800px)" rel="stylesheet" href="example.css"> <?xml-stylesheet media="screen and (width:800px)" rel="stylesheet" href="example.css" ?>列举几种使用方式：
@media all and (width:1024px){ body{color:#f00;} } @media all and (device-height:800px){ … } @media all and (orientation:landscape){ … } @media all and (device-aspect-ratio:16/10){ … } @media all and (min-color:1){ … } @media all and (monochrome:0){ … } @media all and (grid:0){ … }
兼容性(指定媒体类型)：
| IE | Firefox | Chrome | Safari | Opera | iOS Safari | Android Browser | Android Chrome |
|---|---|---|---|---|---|---|---|
| 6.0-8.0 | 2.0+ | 4.0+ | 3.1+ | 15.0+ | 3.2+ | 2.1+ | 18.0+ |
| 9.0+ |
