Question

我尝试过将额外的关键帧（0％，1％，100％或0％，99％，100％）添加到设置-webkit-animation-fill-mode以转发到经常提到的-webkit的所有内容-backface-visibility：hidden;在其他线程中提到的技巧，但在Safari 7（桌面和iOS）的几乎每个动画迭代开始时，我仍然看到我的css关键帧动画中的闪烁。 Chrome似乎没有闪烁。

<div class="ripple"></div>

CSS：

body {

.ripple, .ripple:before, .ripple:after {
  background-image: radial-gradient(circle at 50% 50%, rgba(255, 255, 255, 0) 50%, rgba(255, 255, 255, .15) 100%);

  border-radius: 50%;

.ripple {
  -webkit-animation-name: innerRipple;

在早于99％之间添加帧会使Safari上的闪烁消失！（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; }
}
