Cross-Platform Hover Effects: Transforming :hover into Click/Touch

Mobile devices present a unique challenge for CSS-driven animations triggered by :hover. To ensure a seamless user experience, developers often need to adapt these effects to work with touch or click events. This article explores a simple solution to convert :hover animations to click-based interactions for mobile devices.

The following example demonstrates an animation triggered by :hover on an info bar. When the screen width exceeds 700px, the animation remains triggerable by hover. However, for smaller screens, the animation is modified to be triggered by a click event.

CSS Animation:

.info-slide {
  transition: height .4s ease-in-out;
  height: 60px;
  background: url(../images/blue-back.png);
}

.info-slide:hover {
  height: 300px;
}

Media Query for Responsive Transition:

@media screen and (max-width: 700px) {
  .info-slide {
    cursor: pointer;
  }

  .info-slide:active {
    height: 300px;
  }
}

In this solution, we utilize the :active selector in conjunction with :hover. According to w3schools, this approach effectively transforms the animation into a click or touch-based interaction when the screen width is below 700px.

Testing this solution in a mobile environment verifies that the animation responds accordingly, providing a consistent user experience across devices.
