文字
语法：
monochrome：<integer>
接受min/max前缀：是
取值：
<integer>：
用整数值来定义宽度。不允许负值
说明：
定义在一个单色框架缓冲区中每像素包含的单色原件个数。如果不是单色设备，则值等于0
本特性接受min和max前缀，因此可以派生出min-monochrome和max-monochrome两个媒体特性。
简单列举几个应用示例：
@media screen and (monochrome){ … } @import url(example.css) screen and (monochrome:0); <link media="screen and (min-monochrome:0) and (max-monochrome:10)" rel="stylesheet" href="example.css" /> <?xml-stylesheet media="not screen and (monochrome)" rel="stylesheet" href="example.css" ?>
兼容性：
| Values | IE | Firefox | Chrome | Safari | Opera | iOS Safari | Android Browser | Android Chrome |
|---|---|---|---|---|---|---|---|---|
| Basic Support | 6.0-8.0 | 2.0-3.0 | 4.0-25.0#1 | 6.0#1 | 15.0+ | 6.0-6.1#1 | 2.1-4.3#1 | 18.0-24.0#1 |
| 9.0-11.0#1 | 3.5+ | 26.0+ | 6.1+ | 7.0+ | 4.4+ | 25.0+ |
不支持嵌套媒体查询。
