IE10中介于0％和负％之间的translation3d [英] translate3d between 0% and negative % in IE10

问题描述

我有一个元素需要左右移动到整个宽度的50％。

I have an element that needs to animate left and right to the amount of 50% of its full width.

我已经完成了以下操作（简化了）标记：

I've accomplished this with the following (simplified) markup:

<div class="wrapper">
  <div class="inner">Inner</div>
</div>

样式：

.wrapper {
  position: relative;
  width: 300px;
  height: 200px;
}

.inner {
  position: absolute;
  top: 0; right: 0; bottom: 0; left: 0;
  animation: MOVE_AROUND 5s infinite;
}

具有关键帧动画：

@keyframes MOVE_AROUND {
  0%, 10% { transform: translate3d(0, 0, 0); }
  20%, 40% { transform: translate3d(-50%, 0, 0); }
  60%, 80% { transform: translate3d(50%, 0, 0); }
  90%, 100% { transform: translate3d(0, 0, 0); }
}

注意：为简洁起见，省略了供应商前缀

在IE10中，它没有移动元素宽度的50％，而是在负数中移动了一个较小的（任意值），然后在正数中移动了相同的数量，然后在动画的相位在80％到90％之间，它会捕捉到整个50％的距离，然后又回到0％。

In IE10, instead of moving 50% of the element's width, it moves a smaller (arbitrary?) amount in the negative, then the same amount in the positive, then at the phase of the animation between 80% and 90%, it snaps to the full 50% distance and then back to 0%.

我想这与负百分比，尽管我在其他地方找不到与此有关的任何信息。

I imagine this has something to do with the negative percentage, though I can't find any information regarding this elsewhere.

推荐答案

在2个关键帧之间转换为0时，IE 10似乎出现了一些奇怪的错误。

It appears IE 10 has some strange bug when transitioning between 2 keyframes with a transform of 0.

如果您对两个关键帧使用几乎为零的百分比，那当然不是很理想。 ，您可以在IE 10中达到相同的效果。

While certainly not ideal, if you use an almost-zero percentage for two of your keyframes, you can achieve the same effect in IE 10.

@keyframes MOVE_AROUND_TRANSFORM {
  0% {
    transform: translate3d( 0, 0, 0 );
  }
  10% {
    transform: translate3d( 0.0001%, 0, 0 );
  }
  20%, 40% {
    transform: translate3d( -50%, 0, 0 );
  }
  60%, 80% {
    transform: translate3d( 50%, 0, 0 );
  }
  90% {
    transform: translate3d( 0.0001%, 0, 0 );
  }
  100% {
    transform: translate3d( 0, 0, 0 );
  }
}

或者，您可以在两个关键帧中都使用几乎为零的值。

Alternately, you could just use the almost-zero value in both the keyframes.

@keyframes MOVE_AROUND_TRANSFORM {
  0%, 10% {
    transform: translate3d( 0.0001%, 0, 0 );
  }
  20%, 40% {
    transform: translate3d( -50%, 0, 0 );
  }
  60%, 80% {
    transform: translate3d( 50%, 0, 0 );
  }
  90%, 100% {
    transform: translate3d( 0.0001%, 0, 0 );
  }
}

此问题似乎已在IE 11中解决。

Thankfully this issue appears to have been fixed in IE 11.
