css - 关键帧动画不返回第一点或重复

Question

我正在尝试使用不会返回到第一个位置的关键帧，我的意思是如果我有一个从左到右的过渡，要保持在右边而不是返回到左侧。

代码

div {
  width: 100px;
  height: 100px;
  background-color: red;
  position: relative;
  -webkit-animation-name: example;
  -webkit-animation-duration: 4s;
  animation-name: example;
  animation-duration: 4s;
}

/* Safari 4.0 - 8.0 */

@-webkit-keyframes example {
  0% {
    background-color: red;
    left: 0px;
    top: 0px;
  }
  100% {
    background-color: yellow;
    left: 200px;
    top: 0px;
  }
}


/* Standard syntax */

@keyframes example {
  0% {
    background-color: red;
    left: 0px;
    top: 0px;
  }
  100% {
    background-color: yellow;
    left: 200px;
    top: 0px;
  }
}

<div></div>

你只需要添加 animation-fill-mode: forwards; 到 div。

div {
    width: 100px;
    height: 100px;
    background-color: red;
    position: relative;
    -webkit-animation-name: example; 
    -webkit-animation-duration: 4s; 
    -webkit-animation-fill-mode: forwards;
    animation-name: example;
    animation-duration: 4s;
    animation-fill-mode: forwards;
}

/* Safari 4.0 - 8.0 */
@-webkit-keyframes example {
    0%   {background-color:red; left:0px; top:0px;}
    100% {background-color:yellow; left:200px; top:0px;}
}

/* Standard syntax */
@keyframes example {
    0%   {background-color:red; left:0px; top:0px;}
    100% {background-color:yellow; left:200px; top:0px;}
}

<div></div>
