Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2015.

animation-play-state CSS 属性设置动画是运行还是暂停。

尝试一下

animation-play-state: paused;

animation-play-state: running;

<section class="flex-column" id="default-example">
  <div class="animating" id="example-element"></div>
</section>

#example-element {
  background-color: #1766aa;
  color: white;
  margin: auto;
  margin-left: 0;
  border: 5px solid #333;
  width: 150px;
  height: 150px;
  border-radius: 50%;
}

.animating {
  animation-name: slide;
  animation-duration: 3s;
  animation-timing-function: ease-in;
  animation-iteration-count: infinite;
  animation-direction: alternate;
}

@keyframes slide {
  from {
    background-color: orange;
    color: black;
    margin-left: 0;
  }
  to {
    background-color: orange;
    color: black;
    margin-left: 80%;
  }
}

恢复暂停的动画将从暂停时停止的位置开始播放，而不是从动画序列的开头重新开始播放。
