How Can You Effectively Disable :hover CSS Styles on Touch Devices?

Ignoring :hover CSS Styles on Touch Devices

When developing websites, it's desirable to remove or ignore :hover CSS declarations for touch devices, as these declarations can be awkward and unnecessary.

Quick and Dirty: Using JavaScript

One approach is to use JavaScript to remove all style rules containing :hover. This method is compatible with older browsers and does not require modifying the CSS.

<code class="javascript">function hasTouch() {
  // Check for various touch event APIs.
  ...
}

if (hasTouch()) {
  // Loop through stylesheets and remove :hover rules.
  ...
}</code>

Limitations:

• Stylesheets must be hosted on the same domain.
• Mixed mouse and touch devices can still trigger :hover events, negatively impacting the user experience.

CSS-Only: Media Queries

Alternatively, you can use media queries to disable :hover styles for certain devices.

<code class="css">@media (hover: none) {
  a:hover {
    color: inherit;
  }
}</code>

Limitations:

• Requires media queries, which are not supported by all browsers.
• Does not work on mixed mouse and touch devices.

The Most Robust: JavaScript Detection

For the most reliable solution, detect touch events using JavaScript and prepend :hover rules with a custom class.

<code class="css">body.hasHover a:hover {
  color: blue;
}</code>

<code class="javascript">function hasTouch() {
  // Check for various touch event APIs.
  ...
}

if (!hasTouch()) {
  document.body.className += ' hasHover';
}</code>

This method overcomes the limitations of CSS-only approaches but may still have issues on mixed mouse and touch devices.

To address this, implement a more sophisticated approach that enables hover effects based on mouse cursor movement and disables them on touch events.

<code class="javascript">function watchForHover() {
  // Initialize variables for touch detection.
  ...

  // Add or remove the "hasHover" class depending on user actions.
  ...
}

watchForHover();</code>

This solution provides reliable detection and handling of hover styles on all devices, without compromising the user experience.
