最后无法冻结CSS动画

时间：2019-01-28 15:21:56

标签： html css animation

我有一个CSS动画，我想在最后停止，但它返回到初始状态，尽管我使用的是“ animation-fill-mode：forwards;”。 拜托任何人，动画最初是无限的，所以我将迭代次数设置为1，但现在运行了一次便重置了。

这是Codepen的链接，我正在尝试调整https://codepen.io/donovanh/pen/GgYEBZ

答案 0 :(得分：3)

每个@keyframes动画都有一个最终的“关键帧”，在完成播放之前，它会重置为初始的“状态”。这是91%, 100%周围的动画。删除每个动画的“重置”部分，并使常规动画关键帧在100%处结束。
