Can CSS Transitions Auto-Hide Elements After a Set Time?

Auto-Hiding Elements Using CSS Transitions

Can you make an element disappear 5 seconds after a page loads? While a jQuery solution is known, this article explores how to achieve the same effect using CSS transitions.

Is It Possible?

Yes, but not in the conventional way. Typically, transitions are applied to properties like display, dimensions, or overflow. However, these properties directly control the element's visibility and space occupation.

Innovative Solution

To bypass this limitation, create an animation for the target element. After 5 seconds, toggle its visibility to hidden. Additionally, set its height and width to zero to prevent it from taking up space in the document flow.

Example Implementation

CSS:

#hideMe {
  -webkit-animation: cssAnimation 0s ease-in 5s forwards;
  animation: cssAnimation 0s ease-in 5s forwards;
  -webkit-animation-fill-mode: forwards;
  animation-fill-mode: forwards;
}

@keyframes cssAnimation {
  to {
    width: 0;
    height: 0;
    overflow: hidden;
  }
}

HTML:

<div>

This code sets up an animation that shrinks the element to zero dimensions 5 seconds after the page loads. The element becomes hidden while maintaining its position in the document flow.

Conclusion

While the conventional approach to hiding elements may not be directly applicable, using visibility toggling and zero dimensions in conjunction with CSS animations provides an innovative solution for auto-hiding elements after a specified time interval.
