css - 在 Firefox 60 或更早版本中为 SVG 剪辑路径设置动画时出现随机方 block

Question

我有一个 svg 图像，其中多个元素被剪切路径剪切(全部在文件中定义)。剪辑路径和其中的元素都是动画的。在 Firefox 60 或更早版本中，这些被剪切的元素之一显示为正方形而不是正确的路径: /image/ITTJr.gif

它应该是这样显示的:/image/YQs34.gif

是否有解决方案和/或方法可以在旧版浏览器上使用静态图像作为后备？

Answer 1

我想通了!看起来旧版本的 firefox 根据元素的宽度/高度在元素周围绘制了某种边界框，并且此框不会随元素本身一起设置动画。我通过将元素放在一个组中来修复它，该组中有一个与整个 View 框一样宽/大的不可见矩形。
