使下划线CSS转换更改方向 [英] Make underline CSS transition change direction

问题描述

我使用我在此网站上找到的一些风格以创建有效的下划线幻灯片。请参见 jsfiddle 例如。

如您所见，下划线从左到右向右。我将如何在文本的顶部做另一行，从右到左转换？

I am using some style I found on this website to create an underline slide in effect. Please see jsfiddle for example.
As you can see, the underline comes in from left to right. How would I go about making another line on top of the text, which transitions in from right to left? Could I simply adapt my current code snippet, or would I have to use a different method entirely?

.cmn-t-underline {
  position: relative;
  color: #ff3296;
}
.cmn-t-underline:after {
  display: block;
  position: absolute;
  left: 0;
  bottom: -10px;
  width: 0;
  height: 10px;
  background-color: #2E9AFE;
  content: "";
  -webkit-transition: all 0.3s;
  -moz-transition: all 0.3s;
  -o-transition: all 0.3s;
  transition: all 0.3s;
  height:2px;
}
.cmn-t-underline:hover {
  color: #98004a;
}
.cmn-t-underline:hover:after {
  width: 100%;
	height:2px;
}

<h1 class="cmn-t-underline">Test</h1>

从左向右更改。

.cmn-t-underline:after {
  display: block;
  position: absolute;
  right: 0;
  bottom: -10px;
  width: 0;
  height: 10px;
  background-color: #2E9AFE;
  content: "";
  -webkit-transition: all 0.3s;
  -moz-transition: all 0.3s;
  -o-transition: all 0.3s;
  transition: all 0.3s;
  height:2px;
}
