任何指针 | @media.any-pointer

@media.any-pointer

任何指针式的CSS @media媒体功能都可以根据是否有可用的input机制来应用样式,如果是的话,它是非常精确的。

语法

any-pointer功能指定为从下面列表中选择的关键字值。

none没有指向设备可用。

注:如果可用设备具有不同的特性,则可以匹配多个值,尽管none只有当它们都没有指向设备时才匹配。

例子

HTML

<input id="test" type="checkbox" /> <label for="test">Look at me!</label>

CSS

input[type="checkbox"]:checked { background: gray; } @media (any-pointer: fine) { input[type="checkbox"] { -moz-appearance: none; -webkit-appearance: none; appearance: none; width: 15px; height: 15px; border: 1px solid blue; } } @media (any-pointer: coarse) { input[type="checkbox"] { -moz-appearance: none; -webkit-appearance: none; appearance: none; width: 30px; height: 30px; border: 2px solid red; } }
