IE浏览器.这(拖动拖动阻力被切断)：

应该显示为：

HTML：

<span id="test" class="drag-hint"><span>drag drag drag drag drag</span>Hover me</span>

CSS：

.drag-hint {
  position:relative;
  margin: 50px;
}
.drag-hint > span {
  background: black;
  color: white;
  white-space: Nowrap;
  display:none;
}
.drag-hint:hover > span {
  display: inline;
  position:absolute;
  top: -25px;
  left: 0;
  right: 0;
  text-align: center;
}

解决方法

这是使用CSS3转换的最简单的解决方案.

JSfiddle Demo

.drag-hint {
  position: relative;
  margin: 50px;
  display: inline-block;
  padding: 0 1em;
  border: 1px solid red;
  /* for visual reference */
}
.drag-hint > span {
  background: black;
  color: white;
  white-space: Nowrap;
  display: none;
}
.drag-hint:hover > span {
  display: inline-block;
  position: absolute;
  top: -25px;
  left: 50%;
  transform: translateX(-50%);
  text-align: center;
}

<span class="drag-hint">
    <span>drag drag drag drag drag</span>
Hover me</span>


<span class="drag-hint">
    <span>Lorem ipsum dolor sit amet,consectetur adipisicing elit.</span>
Hover me</span>
