When I hover on font-awesome's icons (when they're stacked together) like below (see picture). I get these strange underlines. Any idea where they could come from?

推荐答案

这些行通常来自默认(下划线)a 元素样式.

Those lines usually come from the default (underline) a element style.

要么使用另一个元素，要么删除下划线:

Either use another element or remove the underline :

a.social { /* or whatever your class */
   text-decoration: none;
}
