如何让 SVG 过滤器也能在 Firefox 上工作？

Question

我使用 SVG 滤镜使 CSS 动画中的顶行发光。它在 Chrome 上工作得很好，但在 Firefox 上却不行。我读到 Firefox 有不同的方式来读取 SVG 过滤器，所以我可能需要添加更多专门用于 Firefox 的代码。我尝试了几件事，但其中 none 成功了。关于如何完成此操作的任何想法？

提前谢谢大家。

body {
  background-color: black;
  height: 100vh;
}

.a1 {
  filter: url(#filter1);
  animation: stroke_fill1 4s linear forwards;
  stroke-dasharray: 850.100;
  stroke-dashoffset: 850.100;
}

@keyframes stroke_fill1 {
  0% {
    fill: black;
  }
  50% {
    fill: black;
    stroke-dashoffset: 0;
  }
  100% {
    fill: rgb(0, 255, 216);
    stroke-dashoffset: 0;
  }
}

.b1 {
  animation: stroke_fill2 4s linear forwards;
  stroke-dasharray: 850.100;
  stroke-dashoffset: 850.100;
}

@keyframes stroke_fill2 {
  0% {
    fill: black;
  }
  50% {
    fill: black;
    stroke-dashoffset: 0;
  }
  100% {
    fill: rgb(149, 149, 149);
    stroke-dashoffset: 0;
  }
}

所以，感谢@RobertLongson，我检查了我的代码，我意识到到处都是无用的东西和错误的语法。这是工作的。再次感谢。

body {
  background-color: black;
  height: 100vh;
}

.a1 {
  filter: url(#filter1);
  animation: stroke_fill1 4s linear forwards;
  stroke-dasharray: 850.100;
  stroke-dashoffset: 850.100;
}

@keyframes stroke_fill1 {
  0% {
    fill: black;
  }
  50% {
    fill: black;
    stroke-dashoffset: 0;
  }
  100% {
    fill: rgb(0, 255, 216);
    stroke-dashoffset: 0;
  }
}

.b1 {
  animation: stroke_fill2 4s linear forwards;
  stroke-dasharray: 850.100;
  stroke-dashoffset: 850.100;
}

@keyframes stroke_fill2 {
  0% {
    fill: black;
  }
  50% {
    fill: black;
    stroke-dashoffset: 0;
  }
  100% {
    fill: rgb(149, 149, 149);
    stroke-dashoffset: 0;
  }
}
