如何防止Safari CSS关键帧动画闪烁? [英] How do I prevent Safari css keyframe animation flicker?
问题描述
我已尝试通过添加额外的关键帧(0%,1%,100%或0%,99%,100%)到设置-webkit-animation-fill-mode来转发tot- -backface-visibility:hidden;在其他线程中提到的伎俩,但我仍然看到我的CSS关键帧动画在几乎每个动画迭代开始的Safari 7(桌面和iOS)闪烁。 Chrome似乎无闪烁。
I've tried everything from adding extra keyframes (0%, 1%, 100% or 0%, 99%, 100%) to setting -webkit-animation-fill-mode to forwards to the oft-mentioned -webkit-backface-visibility: hidden; trick mentioned in other threads, but I'm still seeing a flicker in my css keyframe animation at the start of almost every animation iteration in Safari 7 (both desktop and iOS). Chrome seems to be flicker-free.

推荐答案
一个框架之间有点早在99%使Safari闪烁消失了! (Safari 8 OS X)
Adding a frame in between a little earlier than at 99% made the flickering disappear on Safari! (Safari 8 OS X)
@-webkit-keyframes innerRipple {
0% { height: 0px; width: 0px; opacity: 1; }
95% { height: 200px; width: 200px; opacity: 0; }
100% { width: 0px; height: 0px; opacity: 0; }
}
@-webkit-keyframes ripple {
0% { height: 0px; width: 0px; opacity: 1; }
95% { height: 300px; width: 300px; opacity: 0; }
100% { width: 0px; height: 0px; opacity: 0; }
}
@-webkit-keyframes outerRipple {
0% { height: 0px; width: 0px; opacity: 1; }
95% { height: 340px; width: 340px; opacity: 0; }
100% { width: 0px; height: 0px; opacity: 0; }
}
