这个东西如何在IE/Edge中工作？ 我不明白为什么它没有。
当我向元素添加一个类时，它的边框变为虚线并开始旋转。

<button id = "btn">animate</button>我已经尝试在 trasform 原点中使用 %，并在关键帧中使用 0% 和 100%，就像在一些非常相似的问题中发现的那样。
如果在IE中通过CSS使用，SVG上的转换似乎不起作用，这就是为什么旋转动画不起作用
的原因找到这个SO链接，解释它在SVG元素IE9+上的CSS转换
并且在IE站点中，它被记录为错误 https://connect.microsoft.com/IE/feedback/details/811744/ie11-bug-with-implementation-of-css-transforms-in-svg
