正如标题所说，我正在尝试使用 css 动画制作 SVG 动画。在 chrome 中，svg elements 从 0 不透明度平滑过渡到 1，但在 Firefox 中，它只是直接弹出到 1 不透明度而没有任何延迟或过渡，有时如果我连续刷新页面，那么 10 次它可能会工作一次。在下面的代码中，您将看到我使用其 id 属性在特定 svg 元素上应用了动画，有人可以指出这里可能出了什么问题吗？
.container {
height: 400px;
width: 400px;
}
#circle9114 {
opacity: 0;
animation: appear 1000ms ease-in 250ms forwards;
}
#circle9155 {
opacity: 0;
animation: appear 1000ms ease-in 500ms forwards;
}
#circle9161 {
opacity: 0;
animation: appear 1000ms ease-in 750ms forwards;
}
#circle9161-1 {
opacity: 0;
animation: appear 1000ms ease-in 100ms forwards;
}
@keyframes appear {
to {
opacity: 1;
}
}<div class="container">
