Ruby on Rails link_to 打乱了侧边栏列表元素的对齐方式

Question

添加时：

<%= link_to("Lessons",
  {:controller => 'welcome',
    :action => 'lessons'
  }) %>

它在我的侧边栏上创建了一个新行。 link 应该与地球图标在同一行（地球图标位于正确的位置）。其他 link 看起来是正确的，因为我没有向它们添加 ruby link，以显示没有 ruby link.

参考导航栏： http://blog.codeply.com/2016/05/18/bootstrap-sidebar-responsive-examples/

我在页面底部使用固定宽度的响应式边栏。

HTML 模板：

<!DOCTYPE html>
<html>
<head>
  <title>Workspace</title>
  <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
  <%= csrf_meta_tags %>

Answer 1

这应该可以解决您的问题

<li><%= link_to({:controller => 'welcome',
                :action => 'lessons'
              }) do %>  
<i class="fa fa-globe fa-lg"></i> Lessons
<% end %>
</li>

Answer 2

谢谢@Fabrizio Bertoglio。使用他提供的信息，我添加了这个 css:

.menuitems > a:visited {
  color: #337AB7 !important;
}

.active { 
  background-color: white;
}

.navbar-brand {
  color: white !important;
}

我将菜单项作为 class 添加到每个 link。这允许我的导航栏品牌 class 规则不被 a:visited 覆盖（因为它适用于所有规则）。如果不将该规则应用于特定的菜单项，我的导航品牌字体颜色将不会更改为所需的颜色。

Link 对齐由@Fabrizio Bertoglio 解决：

<li><%= link_to({:controller => 'welcome',
                :action => 'lessons'
              }) do %>  
<i class="fa fa-globe fa-lg"></i> Lessons
<% end %>
</li>
