推荐答案

：hover 伪类需要一个指向（图形输入）设备，能够区分指向和选择/激活。 em>通常在具有触摸界面的移动设备上，您没有前者，只有后者。也有一些笔接口只允许激活，而不指向。

The :hover pseudo-class needs a pointing (graphical input) device, capable of distinguishing the actions pointing and selecting/activating. Usually on mobile devices with a touch interface you don't have the former, only the latter. Also some pen interfaces only allow activating, not pointing.

：hover pseudo -class适用于用户指定元素（使用某些定位设备），但不激活它。例如，当光标（鼠标指针）悬停在由该元素生成的框上时，可视用户代理可以应用此伪类。不支持交互式媒体的用户代理不必支持此伪类。支持交互式媒体的一些符合的用户代理可能不能支持该伪类（例如，笔设备）。

The :hover pseudo-class applies while the user designates an element (with some pointing device), but does not activate it. For example, a visual user agent could apply this pseudo-class when the cursor (mouse pointer) hovers over a box generated by the element. User agents not supporting interactive media do not have to support this pseudo-class. Some conforming user agents supporting interactive media may not be able to support this pseudo-class (e. g., a pen device).

所以，回答你的问题：这取决于设备，但可能没有。而不要依赖它。随着触摸屏设备的迅速普及，您将失去整个指向事件。

So, to answer your question: It depends on the device but likely no. And don't rely on it. With touch-screen devices quickly gaining in popularity you'll lose the entirety of pointing-only events.
