折叠的Navbar - Rails 4 CSS右对齐

我有一个自定义导航栏，我通过使用每个链接的单独div来隔开链接。当宽度<1时768px折叠的链接间隔非常不规则，我想在保留未折叠版本的CSS的同时更正此CSS。

HTML 

<body>
  <nav class="navbar">
    <div class="container-fluid">
      <div class="navbar-header">
        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#collapse-menu">
          <span class="sr-only">Toggle navigation</span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>
        <%= link_to("Brand Name", root_path, { :class => "navbar-brand logo" }) %>
      </div>
      <div class="collapse navbar-collapse" id="collapse-menu">
        <ul class="nav navbar-nav middle-left">
          <li><%= link_to("About", about_path, { :class => "nav-link-custom" }) %></li>
        </ul>
        <ul class="nav navbar-nav middle-right">
          <li><%= link_to("Help", help_path, { :class => "nav-link-custom" }) %></li>
        </ul>
        <ul class="nav navbar-nav navbar-right">
          <li><a class="nav-link-custom" href="#">Sign In</a></li>
        </ul>
      </div>
    </div>
  </nav>

<%= yield %>

</body>

CSS 

/* Navbar */

.logo:hover {
  background: none;
}

.nav > li > a:hover {
  background: none;
}

.middle-left {
  margin-left: 25%;
}

.middle-right {
  margin-left: 10%;
}

.navbar-toggle {
  background: white;
  border: thin solid gray;
}


.icon-bar {
  background: gray;
}

只需使用媒体查询，您的导航就会生成默认的移动导航。

＆＃13; 
/* Navbar */

.navbar .logo:hover {
  background: none;
}
.navbar .nav > li > a:hover {
  background: none;
}
.navbar .navbar-toggle {
  background: white;
  border: thin solid gray;
}
.navbar .icon-bar {
  background: gray;
}
@media (min-width: 768px) {
  .navbar .middle-left {
    margin-left: 25%;
  }
  .navbar .middle-right {
    margin-left: 10%;
  }
}

      <ul class="nav navbar-nav navbar-right">

将margin CSS包含在媒体查询中，以便仅在扩展版本中影响文本。

@media (min-width: 768px) {
  .middle-left {
    margin-left: 25%;
  }

  .middle-right {
    margin-left: 10%;
  }
}
