文字下划线动画从左到右
[英]Text Underline Animation Left to Right
问题描述
The Navigation Links on hover ease in a underline from left to right and ease out right to left. 
悬停时的导航链接从左到右下划线，从右到左下划线。 I would like to make it so that both the ease in & ease out go from left to right. 我想做到这一点，以便轻松进出和轻松进出都从左到右。 How can I adjust the ease out? 如何调整缓和度？

Make some changes to your css: 对您的CSS进行一些更改：
.navlist:after {
...
float: right; /* Add this line */
}
.navlist:hover:after {
...
float: left; /* Add this line */
}
Demo: http://jsfiddle.net/2tycjc82/2/ 演示： http ： //jsfiddle.net/2tycjc82/2/
But as I commented. 但正如我评论。 There's a not-so-nice result when user hover in then immediately hover out. 当用户将鼠标悬停然后立即悬停时，结果会不太好。
