想必大家都知道a超链接锚文本自带下划线样式，为了使页面看着美观，我们会对其做一个处理，让 其下滑线去除。
对于a链接的下划线去除的方法，我们会在css中将text-decoration的值设置为“none”即可。
可当我们的页面加入字体图标时， a链接移入还会出现下划线：

解决方法：
我们需要改 <link rel="stylesheet" href="../style/libs/Font/demo-files/demo.css"/>这个css的样式：
在demo.css中找到它并将其隐藏即可：
a:hover, a:focus { box-shadow: 0 1px #e74c3c; }
你们自己动手试一试吧！
