navbar-right 在引导导航中没有响应

Question

我正在尝试创建一个小型 Sinatra 应用程序。目前，尝试在引导程序的帮助下设置条件导航栏。我正在尝试使用 navbar-right 在右侧显示注册/登录/注销链接，但它无法正常工作。它只显示左侧的所有内容。我的导航栏代码如下所示..

编码技巧

          <!-- Collect the nav links, forms, and other content for toggling -->
          <div >

            <!-- Main nav bar -->
            <ul class="navbar-right nav navbar-nav">
              <% if logged_in? %>
                 <li>
                   <a href="/user/tips">User's tips</a>
                 </li>
                 <li>
                   <a href="/tips/new">New Tip</a>
                 </li>
                 <li>
                   <a href="/logout"> Sign out</a>
                 </li>
                 <% else %>
                  <li>
                    <a href="/signup">Sign Up</a>
                  </li>
                  <li>
                    <a href="/login">Sign In</a>
                  </li>
                <% end %>
                </ul>
          </div><!-- /.navbar-collapse -->
        </div><!-- /.container-fluid -->
      </nav>

我还将 style.css 添加到我的导航栏的自定义样式中，如下所示..

./*///// NAVBAR ////*/
/* while header */
.navbar-default { background-color: #111111; border-color: transparent; -webkit-transition: all 0.35s; -moz-transition: all 0.35s; transition: all 0.35s; font-family: 'Catamaran', 'Helvetica', 'Arial', 'sans-serif'; font-weight: 300; letter-spacing: 1px; font-size: 5em; /* while fixed */ }
.navbar-default .navbar-header .navbar-brand { font-family: 'Arial', 'sans-serif'; font-size: 1em; color: #31002e; font-weight: 200; text-transform: uppercase; padding: 20px 25px; }
.navbar-default .navbar-header .navbar-brand:hover, .navbar-default .navbar-header .navbar-brand:focus { color: #FF0000; }
.navbar-default .navbar-header .navbar-toggle {font-family: 'Arial', 'sans-serif'; font-size: 1em; color: #31002e; font-weight: 200; text-transform: uppercase; padding: 20px 25px;}
.navbar-default .nav > li > a { font-family: 'Arial', 'sans-serif'; text-transform: uppercase; letter-spacing: 2px; font-size: 1em; font-weight: 200; color: #31002e; padding: 20px 25px;  }
.navbar-default .nav > li > a:focus { color: #FF0000; }
.navbar-default .nav > li > a:hover, .navbar-default .nav > li > a:focus:hover { color: #FF0000; }
.navbar-default .nav > li.active > a { color: #FF0000; background-color: #111111; }
.navbar-default .nav > li.active > a:focus { color: #FF0000; background-color: #111111; }
.navbar-default .nav > li.active > a:hover, .navbar-default .nav > li.active > a:focus:hover { background-color: #111111; }
.navbar-default .nav > li > a.selected { color: #fff; background-color: black;}
.navbar-default .affix { background-color: #111111; }
.navbar-default .affix .navbar-header .navbar-brand:hover, .navbar-default .affix .navbar-header .navbar-brand:focus { color: #FF0000; }
.navbar-default .affix .nav > li.active > a { color: #FF0000; }
.navbar-default .affix .nav > li.active > a:focus { color: #FF0000; }
.navbar-default .affix .nav > li > a:hover, .navbar-default .affix .nav > li > a:active, .navbar-default .affix .nav > li > a:focus, .navbar-default .affix .nav > li > a:focus:hover { color: #FF0000; }

有解决这个问题的建议吗？

Answer 1

将pull-right 添加到您的ul 应该可以解决它：

pull-right class 你可以在这里找到源代码：

.pull-right {
  float: right !important;
}
.pull-left {
  float: left !important;
}
