我试图弄清楚为什么Codepen上的此动画不起作用
https://codepen.io/cassie-codes/full/zWJxXj/
您可以在其中找到包含2张图像的气泡动画。一个是背景，第二个是面具。这些随机气泡应移动并显示蒙版图像。在Chrome上有效，在Firefox上无效。我不明白问题是否出在svg属性或CSS上。反正就是代码
HTML：
<div class="bgImage"></div>

scss：

}

@for $i from 1 through 18 {
$a : #{$i*90};
$b : #{$i*90+360};
.blob:nth-child(#{$i}) {
animation: move#{$i} 20s infinite linear;
}
@keyframes move#{$i} {
from {
transform:rotate(#{$a}deg) translate( 200px ,0.1px) rotate(-#{$a}deg);
}
to {
transform:rotate(#{$b}deg) translate( 200px ,0.1px) rotate(-#{$b}deg);

如果需要，可以从scss编译css

当我说它不起作用时，我的意思是气泡不会移动。动画在Firefox上不起作用。但是在Chrome上是的。

来自mozilla的有关CSS transform的开发人员页面：
只能变换盒模型定位的元素。根据经验，如果一个框具有display：块，则该框模型会将其定位。
