Does CSS Hover Functionality Work on Mobile Devices?

Does CSS Hover Functionality Extend to Mobile Devices?

When employing a CSS hover class, web developers often encounter inconsistent behavior between regular and mobile browsers. This discrepancy stems from the hover pseudo-class's dependency on a pointing device to differentiate between "pointing" and "selecting/activating."

Touch-based mobile devices typically lack this distinction, as they only register "activating" actions. Additionally, some pen interfaces also restrict input to "activating" gestures.

According to the W3C specification, the :hover pseudo-class is designed to trigger when a user hovers over an element with a pointing device, without activating it. While some interactive media-supporting user agents may not support this functionality, such as pen devices.

Therefore, the effectiveness of the :hover pseudo-class on mobile devices remains device-dependent. However, it's generally advised to avoid relying on this feature due to the increasing prominence of touch-screen devices, which lack dedicated pointing-only capabilities.
