How Can We Eliminate Sticky Hover Effects on Buttons in Touch-Enabled Environments?

Eliminating Sticky Hover Effects on Buttons in Touch-Enabled Environments

The prevalence of hover effects on buttons creates an issue when it comes to touch devices. The hover state, often indicated by a color change, tends to persist even after tapping the button, resulting in a "sticky" effect. This behavior can be undesirable and interferes with user experience.

To address this issue, numerous approaches have been proposed with varying degrees of success:

• Adding a "no-hover" class on touchend: While this method effectively prevents the hover effect after tapping, it can negatively impact performance and fails to handle devices with both touchscreen and mouse input.
• Adding a "touch" class to the documentElement: This approach also presents challenges in devices that support both touch and mouse input, as it cannot distinguish between the two inputs.

The ideal solution to this problem would be removing the hover state immediately after touching the button. Unfortunately, this functionality is not natively supported by browsers. Attempting to focus another element or manually tap another element do not produce the desired result.

A Perfect Solution:

The implementation of CSS Media Queries Level 4 provides a definitive solution to this problem. Using the following code:

@media (hover: hover) {
    button:hover {
        background-color: blue;
    }
}

browsers that support true hovering (e.g., with mouse input) will apply the hover style only when the hover event is genuine.

For browsers that do not support this feature, a polyfill is available that allows you to emulate the behavior. This polyfill enables you to use the following CSS:

html.my-true-hover button:hover {
    background-color: blue;
}

Finally, using the polyfill's JavaScript, you can dynamically toggle the presence of the "my-true-hover" class based on the device's hover support. This approach effectively replicates the behavior of true hover detection, providing a perfect solution to the sticky hover effect issue on touch devices.
