【问题描述】：

我创建了一个 svg 文件，其中在页面加载时“绘制”了轮廓。动画完成后，我想填充轮廓。

这就是我所做的。

有多个路径。这是一个：

<path id="b1" class="b1" d="M95.4,204.9a31.7,31.7,0,0,1,23,9.6,32.8,32.8,0,0,1,6.9,10.8,38.7,38.7,0,0,1,0,27.4,32.8,32.8,0,0,1-6.9,10.8,31.7,31.7,0,0,1-23,9.6,25.7,25.7,0,0,1-11.9-2.6,25.4,25.4,0,0,1-8.3-6.8v7.7H61V174H75.1v40.3a25.4,25.4,0,0,1,8.3-6.8A25.7,25.7,0,0,1,95.4,204.9Zm-1.7,13.3a19.5,19.5,0,0,0-8,1.6,18.5,18.5,0,0,0-6.1,4.4,19.7,19.7,0,0,0-4,6.6,24.6,24.6,0,0,0,0,16.5,19.7,19.7,0,0,0,4,6.6,18.5,18.5,0,0,0,6.1,4.4,20.9,20.9,0,0,0,16.1-.1,18.1,18.1,0,0,0,6.1-4.5,19.7,19.7,0,0,0,3.9-6.6,24.6,24.6,0,0,0,0-16.1,19.8,19.8,0,0,0-3.9-6.6,18.1,18.1,0,0,0-6.1-4.5A19.6,19.6,0,0,0,93.7,218.2Z" transform="translate(-60.5 -173.5)" fill="none" stroke="#1d1d1b" stroke-miterlimit="10"/>

这是轮廓动画的css：

@keyframes offset{
    to {
        stroke-dashoffset: 0;   
    }   
}

.b1{
    animation: offset 2s linear forwards;
    stroke-dasharray: 324.774;
    stroke-dashoffset: 324.774; 
}

直到这里一切正常。
两秒钟后动画完成，现在我要填充它。
这就是我认为我可以做到的方式：

@keyframes fill {
    0% {
       fill: white;
       }
    100% {
       fill: black;
       }
      }

      #fill {
          animation-name: fill;
          animation-duration: 2s;
          animation-delay:2s;
      }

问题是我已经将id 和class 分配给path
我尝试将path 的id 更改为#fill。

如果我这样做，大纲动画会被覆盖，它只会等待两秒钟。两秒钟后，路径被动画填充。

我怎样才能做到这一点？我想要的是首先为轮廓设置动画，完成后必须填充形状。

谢谢。

【解决方案1】：

您可以在动画中拥有任意数量的关键帧。只需将路径设置为 0% 到 50% 之间的动画，然后将填充设置为 50% 到 100% 之间的动画。

给你：

.b1 {
  animation: stroke_fill 4s linear forwards;
  stroke-dasharray: 324.774;
  stroke-dashoffset: 324.774;
}
@keyframes stroke_fill {
  0% {
    fill: white;
  }
  50% {
    fill: white;
    stroke-dashoffset: 0;
  }
  100% {
    fill: black;
    stroke-dashoffset: 0;
  }
}

<svg width="300" height="300" viewBox="0 0 300 300">
  <path id="b1" class="b1" d="M95.4,204.9a31.7,31.7,0,0,1,23,9.6,32.8,32.8,0,0,1,6.9,10.8,38.7,38.7,0,0,1,0,27.4,32.8,32.8,0,0,1-6.9,10.8,31.7,31.7,0,0,1-23,9.6,25.7,25.7,0,0,1-11.9-2.6,25.4,25.4,0,0,1-8.3-6.8v7.7H61V174H75.1v40.3a25.4,25.4,0,0,1,8.3-6.8A25.7,25.7,0,0,1,95.4,204.9Zm-1.7,13.3a19.5,19.5,0,0,0-8,1.6,18.5,18.5,0,0,0-6.1,4.4,19.7,19.7,0,0,0-4,6.6,24.6,24.6,0,0,0,0,16.5,19.7,19.7,0,0,0,4,6.6,18.5,18.5,0,0,0,6.1,4.4,20.9,20.9,0,0,0,16.1-.1,18.1,18.1,0,0,0,6.1-4.5,19.7,19.7,0,0,0,3.9-6.6,24.6,24.6,0,0,0,0-16.1,19.8,19.8,0,0,0-3.9-6.6,18.1,18.1,0,0,0-6.1-4.5A19.6,19.6,0,0,0,93.7,218.2Z"
