使用关键帧重新启动动画答案

【问题标题】：Restart Animation with Keyframes使用关键帧重新启动动画
【发布时间】：2014-12-24 22:36:10
【问题描述】：

我这辈子都不知道如何重新开始我的动画。这是我到目前为止所达到的地方。它是用 svg 遮罩动画构建的。

我希望它按照目前的状态进行动画处理。但我希望它保持一秒钟或动画的最后 10%，然后在重新开始之前淡出。但是我不知道如何防止动画提前开始。就像它的动画效果很好，但随后它在所有随机部分都动画化了。好郁闷。

这里有人有想法吗？我建错了吗？我相信解决方案在于 CSS 中的 @keyframes

HTML

和 CSS

  svg {
  display:block;
  width:380px;
  height:144px;
  margin: 0 auto;
 }


/*Shape Fills*/

#A, #D, #F {
  fill:#FFA95A;
  }

#B, #E {
  fill:#FF8300;
  }

#C {
  fill:#FFB571;
  }

/* Opacity Animation */

@keyframes fade{
  90%{opacity:1}
  100%{opacity:0}
}

.fade{
  animation:fade infinite running 2s ease-in-out;
}

/*Mask Animations*/

#svg-logo #clipmaskA {
animation: move-mask-1 infinite running 2s ease-in-out;
}

#svg-logo #clipmaskB {
animation: move-mask-2 infinite running 2s ease-in-out;
}

#svg-logo #clipmaskC {
animation: move-mask-3 infinite running 2s ease-in-out;
}

#svg-logo #clipmaskD {
animation: move-mask-4 infinite running 2s ease-in-out;
}

#svg-logo #clipmaskE {
animation: move-mask-5 infinite running 2s ease-in-out;
}

#svg-logo #clipmaskF {
animation: move-mask-6 infinite running 2s ease-in-out;
}

/* Mask Translations */

@keyframes move-mask-1 {
  0% {transform: translate(-99.99%,0%)}
  15% {transform: translate(0,0)}
}

@keyframes move-mask-2 {
  16% {transform: translate(-18%,99.99%)}
  30% {transform: translate(0,0)}
}

@keyframes move-mask-3 {
  31% {transform: translate(-99.99%,-99.99%)}
  45% {transform: translate(0,0)}
}

@keyframes move-mask-4 {
  46% {transform: translate(-99.99%,99.99%)}
  60% {transform: translate(0,0)}
}

@keyframes move-mask-5 {
  61% {transform: translate(-20%,-99.99%)}
  75% {transform: translate(0,0)}
}

@keyframes move-mask-6 {
  76% {transform: translate(-99.99%,0)}
  90% {transform: translate(0,0)}
}

【解决方案1】：

我刚刚发现，在每个 @keyframe 动画开始时，我需要进行 0% 的平移，以匹配下一步的蒙版位置。

之前

@keyframes move-mask-2 {
  16% {transform: translate(-18%,99.99%)}
  30% {transform: translate(0,0)}
}

我通过添加 0% 的行来修复它

@keyframes move-mask-2 {
  0%% {transform: translate(-18%,99.99%)}
  16% {transform: translate(-18%,99.99%)}
  30% {transform: translate(0,0)}
}
