javascript - 动画 SVG 路径元素

我有一个 SVG，里面有一些路径。我想将这些路径向下移动大约 100 像素并让它们淡出。我最终会使用 Javascript 来重复这个动画。现在，我已经创建了 CSS 动画并将类附加到每个元素，但它似乎不起作用。如果我在 Web 检查器中查看并切换翻译属性，动画将按预期工作。不过，它似乎不适用于页面加载。

我可能处理错了，我真的很感激一个解决方案。

这是代码的链接:

最佳答案

您想分别为每个水滴制作动画吗？如果没有，我已经设置了一个带有 animation 属性的动画。

这是一个片段

body {
  background: #000;
}
.st0 {
  fill: #FFFFFF;
}
.drop {
  display: block;
  position: relative;
  animation: drop 2.5s;
  animation-iteration-count: infinite;
}
@keyframes drop {
  from {
    transform: translateY(0px);
    opacity: 1.0;
  }
  to {
    transform: translateY(50px);
    opacity: 0;
  }
}
