scale 与 transfrom-origin配合出现奇特效果

代码如下：

第一种：这个方法在Edge和IE浏览器不起作用

<div>Hover Me</div>

div {
  position: absolute;
   200px;
  height: 60px;
  font-size: 30px;
  text-align: center;
  transition: all 0.5s;
  -webkit-transition: all 0.5s;
  -moz-transition: all 0.5s;
  -ms-transition: all 0.5s;
}
div::before {
  content: "";
  position: absolute;
  left: 0;
  bottom: 0;
   200px;
  height: 60px;
  background: deeppink;
  transform: scaleX(0);
  transition: all 0.5s;
  -webkit-transition: all 0.5s;
  -moz-transition: all 0.5s;
  -ms-transition: all 0.5s;
  transform-origin: 0 0;
  z-index: -1;
}
div:hover {
  color: #fff;
}
div:hover:before {
  transform: scaleX(1);
  transform-origin: 100% 0;
}

第二种：兼容Edge和IE9以上浏览器

div {
  margin-top: 60px;
  padding: 20px;
  font-size: 26px;
  position: relative;
  overflow: hidden;
  display: inline-block;
  transition: all 0.5s;
  -webkit-transition: all 0.5s;
  -moz-transition: all 0.5s;
  -ms-transition: all 0.5s;
}
div:before {
  content: '';
   100%;
  height: 100%;
  position: absolute;
  left: 0;
  top: 0;
  background: #d3817a;
  opacity: 0;
  transform: translateX(-100%);
  transition: transform 0.5s ease-in-out 0s;
  z-index: -1;
}
div:after {
  content: "";
   100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
  background: #d3817a;
  opacity: 1;
  transform: translateX(100%);
  transition: transform 0.5s ease-in-out 0s;
  z-index: -1;
}
div:hover {
  color: #fff;
}
div:hover:before {
  opacity: 1;
  transform: translateX(0px);
}
div:hover:after {
  opacity: 0;
  transform: translateX(0%);
}
