CSS Basics: animation-play-state

CSS animations have become an integral part of modern web design, allowing developers to bring websites to life with dynamic and engaging visual effects. One important property that controls the playback of CSS animations is animation-play-state. In this article, we will explore the basics of this property and how it can be used to enhance the user experience on your website.

Understanding animation-play-state

The animation-play-state property is used to control the playback of CSS animations. It accepts two values: running and paused. By default, animations are set to running, which means they will play continuously. However, by changing the value to paused, you can pause the animation at any given point.

Let's take a look at an example:

@keyframes slide-in {
  0% {
    transform: translateX(-100%);
  }
  100% {
    transform: translateX(0);
  }
}

.slide {
  animation-name: slide-in;
  animation-duration: 1s;
  animation-play-state: running;
}

In the above example, we define a simple animation called slide-in that slides an element from left to right. The .slide class applies this animation to an HTML element. By default, the animation will start playing as soon as the page loads.

Controlling animation playback

Now, let's say we want to give the user the ability to pause and resume the animation by clicking on the element. We can achieve this by using JavaScript to toggle the value of the animation-play-state property.

const slideElement = document.querySelector('.slide');

slideElement.addEventListener('click', function() {
  if (slideElement.style.animationPlayState === 'running') {
    slideElement.style.animationPlayState = 'paused';
  } else {
    slideElement.style.animationPlayState = 'running';
  }
});

In the above JavaScript code, we select the element with the class .slide and add a click event listener to it. When the element is clicked, we check the current value of the animation-play-state property. If it is set to running, we change it to paused, and vice versa.

Conclusion

The animation-play-state property is a powerful tool for controlling the playback of CSS animations. By using this property, you can create interactive and engaging animations that enhance the user experience on your website. Whether you want to pause an animation on user interaction or create a play/pause button, the animation-play-state property gives you the flexibility to do so.
