IE / Edge CSS3转换不适用于background-position属性

我知道我在谈论IE,但我认为 transition属性已在更近期(Edge?)版本中得到修复。

我尝试转换元素的background-position(请参阅下面的演示),但无论出于何种原因,它都无法在IE中运行......:&#39 ;-(

在下面的演示中,"点击我"按钮应该突出显示相邻的文本,但不适用于IE。

如果您切换"切换显示"按钮,您将看到背景颜色显示(当然过渡后),因为切换display:none正在强制重绘。我知道background-size可能不是transition - 能够在IE中使用,但是这会影响background-position上的单个过渡属性吗?任何方式让这种背景颜色从左到右转换(请参阅IE以外的任何其他浏览器中的演示以获得所需的效果)?

谢谢!



/** JS only to facilitate the test and trigger the CSS on button click **/
var myHighlighter = document.querySelector('.button');
var myToggle = document.querySelector('.toggle');

myHighlighter.addEventListener('click', press)
// toggling `display:none` just forces a repaint
myToggle.addEventListener('click', toggle);

function press(e) {
  var newState = (e.target.getAttribute('aria-pressed')!=="true");
  e.target.setAttribute('aria-pressed', newState);
}

function toggle(e) {
  var isToggled = (e.target.previousElementSibling.getAttribute('style'))
  if (isToggled) {
    e.target.previousElementSibling.removeAttribute('style');
  } else {
    e.target.previousElementSibling.setAttribute('style', 'display:none;');
  }
}

/* conditional CSS for transition based on presence of `aria-pressed="true"` attribute */
.button + .text {
  background: linear-gradient(to right, orange 50%, transparent 50%) no-repeat;
  background-position:right bottom;
  background-size: 200% 100%;
  transition: none;
}

.button[aria-pressed="true"] + .text {
  background-position: left bottom;
  transition: background-position .5s linear;
}

<div class="wrapper">
  <button type="button"
        class="button"
        aria-pressed="false"> 
        Click Me
  </button>

  <span class="text">IE won't transition the background-position (color highlighting) initially without toggleing the display (repaint)</span>
  <button class="toggle">Toggle Display</button>
  
</div>

将过渡属性移动到第一个集合,所以它看起来像这样:

.button + .text {
background: linear-gradient(to right, orange 50%, transparent 50%) no-repeat;
background-position:right bottom;
background-size: 200% 100%;
transition: background-position .5s linear;
}

.button[aria-pressed="true"] + .text {
background-position: left bottom;
}

抱歉,我无法弄清楚如何将您的代码段添加到我现有的答案中......

添加到您的CSS:

.text {
display:block;
}

这使它在IE中运行。这是您编辑的代码: https://jsfiddle.net/kellyking/2zLhz8t6/2/
