How to create a staggered animation effect on a list of items?

list Interleaved animation

To achieve the staggered animation effect of list items, the key is to control the animation triggering timing of each element. 1. Use CSS animation animation-delay to achieve staggered effects by setting incremental delay time for each list item; 2. Use JavaScript to dynamically set delays, suitable for dynamically generated content, and automatically add different delays to each element; 3. Use @keyframes to define animation styles to ensure that the animation effects are unified and customizable; 4. Pay attention to performance and compatibility, avoid complex animations and excessive nesting, and improve user experience.

How to create a staggered animation effect on a list of items?

To achieve the staggered animation effect of a list item, the core is to make each element appear slightly "staggered" in time or order. This effect is often used in scenes such as page loading, menu expansion, card display, etc., which can enhance the visual rhythm and interactive experience.

1. animation-delay using CSS

This is the most common and easiest way to achieve. The principle is to add an animation to each list item, and then set different animation-delay to achieve the effect of staggered playback.

 .item {
  opacity: 0;
  transform: translateY(20px);
  animation: fadeInUp 0.6s ease forwards;
}

.item:nth-child(1) { animation-delay: 0.1s; }
.item:nth-child(2) { animation-delay: 0.2s; }
.item:nth-child(3) { animation-delay: 0.3s; }
/* and so on*/

Key points:

  • Unified animation styles (such as fading in and moving upward)
  • Each child's delay time is incremented
  • Please note that the total animation duration should not be too short, otherwise you will not be able to see the erroneous feeling.

2. Dynamically set delay using JavaScript (suitable for dynamic content)

If your list is dynamically generated, such as obtaining data from the interface and rendering it, it is not realistic to manually write multiple nth-child at this time. You can automatically add delay to each element when rendering in JS.

 document.querySelectorAll('.item').forEach((el, index) => {
  el.style.animationDelay = `${index * 0.1 0.1}s`;
});

In this way, no matter how many items there are, the animation can be played in sequence. Suitable for execution after component mount is completed in React, Vue and other frameworks.

3. Use @keyframes to define animation styles

Whether you use CSS or JS to control the animation itself, the style of the animation itself must be defined by @keyframes . For example:

 @keyframes fadeInUp {
  from {
    opacity: 0;
    transform: translateY(20px);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}

You can adjust the starting state and duration of the animation as needed, such as changing it to zoom, rotation and other effects. As long as you cooperate with the delay, you can create rich staggered animation effects.

4. Additional advice: Pay attention to performance and compatibility

  • Don't use too complex animations , especially on mobile, excessive transformation or opacity may affect the frame rate.
  • Avoid too many nested animations . If the parent container is also moving, it may appear confusing to make the child erroneous animations.
  • Consider initial hiding , for example, set visibility: hidden first, and then change to visible when the animation ends, to prevent elements from flashing suddenly before the animation.

Basically that's it. The staggered animation looks cool, but it is not complicated to implement. The key is to control the triggering timing of each element.
