关于javascript:Css3无缝滚动防抖

问题

图片加文字的无缝滚动，在手机端的成果总体还行，然而图片在手机某些浏览器会抖得腻害！

谬误写法

不能用 left，margin-left, 像这种写法:

.donghua.active{
  animation: scoll ease-in-out 1s infinite alternate;
  -webkit-animation: scoll ease-in-out 1s infinite alternate;
}
@keyframes scoll  {
  from {left: 0;}
  to {left: -353px;}
}
-webkit-@keyframes scoll  {
  from {left: 0;}
  to {left: -353px;}
}

办法

外面的某个元素在手机端会抖动的腻害, 改用二维的 translate 像这样:

.donghua.active{
  animation: scoll ease-in-out 1s infinite alternate;
  -webkit-animation: scoll ease-in-out 1s infinite alternate;
}
@keyframes scoll {
  0% {transform: translate(0px, 0px);
  }

  100% {transform: translate(0px, -353px);
  }
}
@-webkit-keyframes scoll {
  0% {transform: translate(0px, 0px);
  }

  100% {transform: translate(0px, -353px);
  }
}
