我已经创建了一个SVG加载指示器。它在Chrome等人工作正常，但我似乎无法在IE10中使用它 - 这里是小提琴：https://jsfiddle.net/288mu88o/
@keyframes loading {
0% {
fill: red;
}
100% {
fill: yellow;
}
}
.c1, .c2, .c3, .c4, .c5, .c6, .c7, .c8, .c9, .c10, .c11, .c12, .c13, .c14, .c15 {
animation: loading 1.5s infinite;
}
.c1 {
animation-delay: 1.4s;
}
.c2 {
animation-delay: 1.3s;
}
.c3 {
animation-delay: 1.2s;
}
...
<g>
<circle fill="#D9E2E7 " cx="294.7" cy="342.1" r="3.5" class="c1" />
</g>
<g>
<circle fill="#D9E2E7 " cx="281.3" cy="344.8" r="3.5" class="c2"/>
</g>
<g>
<circle fill="#D9E2E7 " cx="270.2" cy="352.7" r="3.5" class="c3"/>
</g>

我错过了什么？
感谢。
