解决方案

我会这样做：

我正在使用您的路径作为剪切路径：<clipPath id="clip">. 我使用 SVG 元素代替图像，通过将stroke-dashoffset属性的值从 80（总长度）更改为 0 来为线条设置动画。每个动画在前一个动画结束时开始。

.ab-container {
  display: flex;
  flex-direction: row;
  width: 100%;
  justify-content: space-between;
  max-width: 400px;
  height: 80px;
  border: 1px solid black;
  align-items: center;
  padding: 20px;
}

line {
  stroke: #ffd328;
  clip-path: url(#clip);
  stroke-width: 11;
  stroke-dasharray: 80;
}

</clipPath>
</svg>

这就是我使用 CSS 动画的方式。逻辑和之前一样。我正在使用路径来剪辑线条，并且我正在将 stroke-dashoffset 从 80 设置为 0。
