Is There A Callback On Completion Of A Css3 Animation

If you've ever wondered if there's a way to trigger a callback when a CSS3 animation finishes, you're in luck! Callbacks are essential for handling events when an animation completes, providing developers with the ability to create seamless transitions and interactions on their websites or applications. In this article, we'll explore how you can achieve this functionality using JavaScript and CSS animations.

CSS animations offer a powerful way to add visual effects to your web projects without the need for external libraries or plugins. However, one limitation of CSS animations is the lack of built-in callbacks to execute code upon completion. So, how can you work around this limitation?

To address this issue, you can leverage the power of JavaScript to detect when a CSS3 animation finishes and then execute the desired callback function. By combining CSS animations with JavaScript, you can create dynamic and interactive animations that respond to user interactions and events in real-time.

One approach to implementing a callback on the completion of a CSS3 animation is by using the `animationend` event in JavaScript. This event is triggered when a CSS animation reaches the end of its duration. By listening for this event on the animated element, you can run your callback function once the animation has finished playing.

Here's a simple example demonstrating how you can use the `animationend` event to execute a callback function after a CSS3 animation completes:

<div class="box"></div>


  .box {
    width: 100px;
    height: 100px;
    background: red;
    animation: example 2s;
  }

  @keyframes example {
    to {
      background: blue;
    }
  }



  const box = document.querySelector('.box');

  box.addEventListener('animationend', () =&gt; {
    // Your callback function here
    console.log('Animation finished!');
  });

In this code snippet, we have a simple box element with a CSS animation applied to change its background color from red to blue over a duration of 2 seconds. We then listen for the `animationend` event on the box element and log a message to the console when the animation finishes.

By incorporating this pattern into your projects, you can enhance the user experience with smooth animations that seamlessly transition between states. Whether you're building a portfolio website, a web application, or an interactive game, callbacks on CSS3 animations can help you achieve the desired level of interactivity and engagement.

In conclusion, leveraging JavaScript to trigger a callback upon the completion of a CSS3 animation opens up a world of possibilities for creating dynamic and engaging web experiences. By combining the power of CSS animations with JavaScript's event handling capabilities, you can take your projects to the next level and captivate your audience with visually stunning effects. So go ahead, experiment with callbacks on CSS3 animations, and bring your designs to life!
