Question

我目前正在使用active_link_to来跟踪导航栏链接状态的变化。当我将样式添加到活动状态时，它看起来如下图所示。我想将活动状态边界推到链接的顶部。 Twitter的导航栏就是我一直试图实现的风格的一个很好的例子。最后，当一个链接只显示边界活动状态时，似乎所有状态当前都在导航栏中处于活动状态。

Awesome_link生成

下面的链接标记

<a href="/"><i class="fa fa-arrow-circle-o-up"></i></a>

CSS

 nav a.active {
      border-style: solid;
      border-top: thick solid #27CCC0;
    }

Answer 1

我想知道你是否可以同时使用active_link_to和awesome_link来生成a元素。

  <li class="nav-item">
          <%= active_link_to awesome_link 'fa fa-home fa-3x', home_path, :class => 'nav-item nav-link', title: 'Home', style: 'color: white' %>
        </li>

用

替换上面的内容

  <li class="nav-item">
          <%= active_link_to '<i class="ffa fa-home fa-3x" style="color:white"></i>', home_path, :class_active => 'nav-link active', :class_inactive => 'nav-link' %>
    </li>

如何使用active_link_to直接在有效链接上定位边框？ Rails 4
