奇怪的字体强大的CSS下划线

Question

当我将font-awesome的图标(当它们堆叠在一起时)悬停在下面时(见图).我得到了这些奇怪的下划线.知道他们可以来自哪里？

资源:

 <div class="text-center">
          <!-- FB -->
          <a href="http://www.facebook.com/share.php?u=${shareURL}"
             target="_blank" style="color : #555">
            <i id="facebook" class="fa-3x fa fa-facebook-square"></i>
          </a>
          <!-- Twitter -->
          <a href="http://twitter.com/?status=Sign-Up+for+SolidTranslate+here!:+${shareURL}+@SolidTranslate" target="_blank" style="color : #555">
            <i id="twitter" class="fa-3x fa fa-twitter-square"></i>
          </a>
        <!-- LinkedIn -->
        <a href="http://www.linkedin.com/shareArticle?url=${shareURL}&title=Sign-Up%20for%20SolidTranslate%20here:%20${shareURL}&summary=To%20get%20started%20translating%20SolidWorks%20files%20register%2\

          <i id="linkedin" class="fa-3x fa fa-linkedin-square"></i>
        </a>
        <!-- Google+ -->
        <a href="https://plus.google.com/share?url=${shareURL}"
           target="_blank"
           style="color : #555">
          <i id="googleplus" class="fa-3x fa fa-google-plus-square"></i>
        </a>

Answer 1

这些行通常来自默认(下划线)a元素样式.

使用其他元素或删除下划线:

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

Answer 2

"text-decoration:none;" 需要在"a"标签上设置":hover"选择器,就像这样......

a:hover { text-decoration: none; }
