动画延迟在 iOS 上无法正常工作，为什么？

Question

我在代码片段中有以下代码。它在除 iOS 以外的任何地方都可以正常工作 - 我想问题在于动画延迟，因为一些动画段落是同时动画的。可以看演示http://stassabiomassa.com/（左龙头出来的字）

有人知道这个问题吗？请帮忙。谢谢！

解决了。如果将动画延迟设置为负值，则可以正常工作。对于每个 ":nth-of-type(n)" 如下：

animation-delay: -9.8s;
animation-delay: -11.8s;
animation-delay: -13.8s;
animation-delay: -15.8s;
animation-delay: -17.8s;
