css - Bootstrap 选项卡 - 自定义样式

Question

我正在尝试在类似于下面的屏幕截图的 Bootstrap 选项卡上实现相同类型的“箭头”样式。我怎样才能实现类似的目标？

我在 jsfiddle 中有我的示例代码，我在其中使用了 Bootstrap 选项卡。

<div>
  <!-- Nav tabs -->
  <ul class="nav nav-tabs" role="tablist">
    <li role="presentation">
        <a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a>     </li>
    <li role="presentation" class="active">
        <a href="#office" aria-controls="profile" role="tab" data-toggle="tab">Office</a>
    </li>
    <li role="presentation">
        <a href="#confirmation" aria-controls="profile" role="tab" data-toggle="tab">Confirm</a>
    </li>
  </ul>

  <!-- Tab panes -->
  <div class="tab-content">
    <div role="tabpanel" class="tab-pane" id="home">Home</div>
    <div role="tabpanel" class="tab-pane active" id="office">Office</div>
    <div role="tabpanel" class="tab-pane" id="confirmation">Confirm</div>

  </div>
