html - Bootstrap 3 - 如何在折叠的导航栏中正确显示按钮 (btn-navbar)？

Question

我使用以下 HTML 代码制作了一个包含 3 个按钮 (btn-navbar) 的页脚。当导航栏折叠时，我可以正确地切换它，但是按钮全部显示在同一行中，而不是像 <li> 那样一个一个地显示在彼此之上。元素。

  <!-- Fixed navbar bottom -->
  <div class="navbar navbar-default navbar-fixed-bottom" role="navigation">
    <div class="container-fluid">

      <div class="navbar-collapse collapse" id="navbar-footer">

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

          <button type="button" class="btn btn-warning navbar-btn"><span class="glyphicon glyphicon-check"></span> Verificar</button>
          <button type="button" class="btn btn-danger navbar-btn"><span class="glyphicon glyphicon-remove"></span> Cancelar</button>
          <button type="button" class="btn btn-success navbar-btn"><span class="glyphicon glyphicon-ok"></span> Aceptar</button>

        </ul>

      </div><!--/.nav-collapse -->

      <div class="navbar-header">
        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#navbar-footer">
          <span class="sr-only">Toggle navigation</span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>

      </div>

    </div>
  </div>

显示是这样的...

我希望它像这样显示...

提前致谢。

您在 ul 中缺少 li。 HTML 标记问题:

 <ul class="nav navbar-nav navbar-right">
   <li><button type="button" class="btn btn-warning navbar-btn"><span class="glyphicon glyphicon-check"></span> Verificar</button></li>
   <li><button type="button" class="btn btn-danger navbar-btn"><span class="glyphicon glyphicon-remove"></span> Cancelar</button></li>
   <li><button type="button" class="btn btn-success navbar-btn"><span class="glyphicon glyphicon-ok"></span> Aceptar</button></li>
 </ul>
