在 Edge 和 IE 上是否有动画 SVG（使用 CSS）的解决方法？
Is there a workaround for animated SVGs (using CSS) on Edge and IE?
我有一个 SVG 动画，它不能在 Edge 上运行，显然不能在 IE 上运行。我已经对这个问题进行了广泛的研究，并且知道为 stroke-dashoffset 和 stroke-dasharray 使用像素以使其工作。我做了同样的事情，但没有用。现在，据我所知，Edge 目前支持 SVG 动画；再一次，它对我不起作用。
我想知道是否有任何解决方法，比如在动画不工作时使用背景图像的方法？我搜索了很多，但找不到相关主题。任何想法将不胜感激。

问题似乎是因为 IE 不支持 SVG animation。
我认为最简单的解决方法是在 IE 中使用 gif。我制作了动画的 gif 并使用 this tool. The outcome gif is like this 将其循环计数为一次。我们可以使用 IE 特定的 css 规则来显示 gif 并在 IE 中隐藏其他部分：
@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
/* IE10+ CSS */
#gif-img{
display:block;
}
.banner__1__content--l2 svg-text--container {
display: none;
}
}
<div id="gif-img">
<img src="https://i.stack.imgur.com/jrK6Y.gif" />
</div>
<div class="banner__1__content--l2 svg-text--container">
...
</div>
在 Edge 中，我发现如果我们将 stroke-width 的值设置得足够大，动画就会起作用。但是结果还是和Chrome和the New Edge Chromium有点不同（你可以尝试更新到最新的Edge Chromium官方构建）：
@supports (-ms-ime-align: auto) {
/* Edge 16+ CSS */
.svg-text {
stroke-width: 700px;
}
}
我有一个 SVG 动画，它不能在 Edge 上运行，显然不能在 IE 上运行。我已经对这个问题进行了广泛的研究，并且知道为 stroke-dashoffset 和 stroke-dasharray 使用像素以使其工作。我做了同样的事情，但没有用。现在，据我所知，Edge 目前支持 SVG 动画；再一次，它对我不起作用。
我想知道是否有任何解决方法，比如在动画不工作时使用背景图像的方法？我搜索了很多，但找不到相关主题。任何想法将不胜感激。

问题似乎是因为 IE 不支持 SVG animation。
我认为最简单的解决方法是在 IE 中使用 gif。我制作了动画的 gif 并使用 this tool. The outcome gif is like this 将其循环计数为一次。我们可以使用 IE 特定的 css 规则来显示 gif 并在 IE 中隐藏其他部分：
@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
/* IE10+ CSS */
#gif-img{
display:block;
}
.banner__1__content--l2 svg-text--container {
display: none;
}
}
<div id="gif-img">
<img src="https://i.stack.imgur.com/jrK6Y.gif" />
</div>
<div class="banner__1__content--l2 svg-text--container">
...
</div>
在 Edge 中，我发现如果我们将 stroke-width 的值设置得足够大，动画就会起作用。但是结果还是和Chrome和the New Edge Chromium有点不同（你可以尝试更新到最新的Edge Chromium官方构建）：
@supports (-ms-ime-align: auto) {
/* Edge 16+ CSS */
.svg-text {
stroke-width: 700px;
}
}
