How Can We Prevent Sticky Hover Effects on Buttons for Touch Devices?

Preventing Sticky Hover Effects on Touch Devices for Buttons

When creating user interfaces for both desktop and touch-enabled devices, it's crucial to address the issue of sticky hover effects on buttons. On touch devices, the hover state, which is typically indicated by changing the element's background color, can become stuck, even after the button has been released.

Solutions to Prevent Sticky Hover Effects

Several solutions have been proposed to address this issue:

• Removing the hover class: Although this method is simple, it can be inefficient and may not work well on devices that support both touch and mouse input.
• Adding a touch class: This technique also has limitations, as it doesn't account for devices with mixed input methods.

The Preferred Solution

The ideal solution would be to remove the hover state on touchend. However, this seems unachievable through conventional methods like focusing another element or triggering manual tapping in JavaScript.

Media Queries Level 4 Solution

However, with the widespread implementation of CSS Media Queries Level 4 since 2018, there's a more elegant solution available:

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

This CSS rule states that when the browser supports true hovering (typically indicating the use of a mouse-like primary input device), the hover stylings will be applied to buttons. This effectively prevents hover effects on touch-enabled devices.

Polyfill for Legacy Browsers

For browsers that don't support CSS Media Queries Level 4, a polyfill can be used to implement a similar solution:

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

JavaScript code from the polyfill can then toggle the my-true-hover class based on hovering support:

$(document).on('mq4hsChange', function (e) {
    $(document.documentElement).toggleClass('my-true-hover', e.trueHover);
});

By using this solution, developers can ensure that buttons have appropriate hover effects on desktop browsers while preventing sticky hover effects on touch-enabled devices.
