Why Doesn\'t My CSS Hover Effect Work on Mobile Devices?

CSS Hover and Mobile Compatibility

Question:

Why does my CSS hover class function on web browsers but not on mobile browsers?

Answer:

The :hover pseudo-class utilizes a pointing device for activation. Mobile devices with touch interfaces lack this feature, as they only permit selection.

As explained by W3C:

"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."

Key Considerations:

• Compatibility with mobile devices varies.
• Reliance on :hover is discouraged due to the increasing prevalence of touch-screen devices, which may not support these events.
• Alternative solutions, such as JavaScript-based mouseover effects, may be necessary for cross-platform compatibility.
