关键帧在 IE11 中无法正常工作

Question

我有一个选择框动画，其中突出显示了选择框。显然，关键帧动画在 Chrome 中可以正常工作，但在 IE11 中不能正常工作。我想知道我应该在代码中更改什么，以便它也能在 IE11 中工作。

.animate-box{
    height: 100%;
    -moz-animation-duration: 0.5s;
      -webkit-animation-duration: 0.5s;
      -moz-animation-name: changeShadow;
      -webkit-animation-name: changeShadow;
      -moz-animation-iteration-count: infinite;
      -webkit-animation-iteration-count: infinite;
      -moz-animation-direction: alternate;
      -webkit-animation-direction: alternate;
    border: 1px solid black;
}
@-webkit-keyframes changeShadow{
  from {
    box-shadow: 0px 0px 10px #90a4b2;
  }

  to {
    box-shadow: 0px 0px 20px #337ab7;
  }
}

@-moz-keyframes changeShadow{
  from {
    box-shadow: 0px 0px 10px #90a4b2;
  }

  to {
    box-shadow: 0px 0px 20px #337ab7;
  }
}

<select class="animate-box">
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

我发现我忘记将动画属性添加到 css 并包含无前缀关键帧:

.animate-box{
    height: 100%;
    -moz-animation-duration: 0.5s;
    -webkit-animation-duration: 0.5s;
    animation-duration: 0.5s;
    -moz-animation-name: changeShadow;
    -webkit-animation-name: changeShadow;
    animation-name: changeShadow;
    -moz-animation-iteration-count: infinite;
    -webkit-animation-iteration-count: infinite;
    animation-iteration-count: infinite;
    -moz-animation-direction: alternate;
    -webkit-animation-direction: alternate;
    animation-direction: alternate;
    border: 1px solid black;
}

@keyframes changeShadow{
  from {
    box-shadow: 0px 0px 10px #90a4b2;
  }

  to {
    box-shadow: 0px 0px 20px #337ab7;
  }
}

您必须为 IE10+ 的 CSS 动画添加无前缀属性，请在 CanIUse?. Also, you could use shorthand animation 上查看属性:

.animate-box {
    height: 100%;
    -webkit-animation: changeShadow 0.5s infinite alternate;
    -moz-animation: changeShadow 0.5s infinite alternate;
    animation: changeShadow 0.5s infinite alternate;
    border: 1px solid black;
}
@-webkit-keyframes changeShadow {
  from { box-shadow: 0 0 10px #90a4b2; }
  to { box-shadow: 0 0 20px #337ab7; }
}

@-moz-keyframes changeShadow {
  from { box-shadow: 0 0 10px #90a4b2; }
  to { box-shadow: 0 0 20px #337ab7; }
}

@keyframes changeShadow {
  from { box-shadow: 0 0 10px #90a4b2; }
  to { box-shadow: 0 0 20px #337ab7; }
}

<select class="animate-box">
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>
