将导航选项卡和选项卡窗格放在同一个 div 中有什么好处吗？

Question

在 bootstrap 版本 3 的 Toggable Tabs 文档中，导航选项卡和选项卡窗格位于同一 div 中。这样做有什么好处吗？

<div>

  <!-- Nav tabs -->
  <ul class="nav nav-tabs" role="tablist">
    <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
    <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>
    <li role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li>
    <li role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li>
  </ul>

  <!-- Tab panes -->
  <div class="tab-content">
    <div role="tabpanel" class="tab-pane active" id="home">...</div>
    <div role="tabpanel" class="tab-pane" id="profile">...</div>
    <div role="tabpanel" class="tab-pane" id="messages">...</div>
    <div role="tabpanel" class="tab-pane" id="settings">...</div>
  </div>

</div>

与刚刚拥有

相比

<!-- Nav tabs -->
<ul class="nav nav-tabs" role="tablist">
  <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
  <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>
  <li role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li>
  <li role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li>
</ul>

<!-- Tab panes -->
<div class="tab-content">
  <div role="tabpanel" class="tab-pane active" id="home">...</div>
  <div role="tabpanel" class="tab-pane" id="profile">...</div>
  <div role="tabpanel" class="tab-pane" id="messages">...</div>
  <div role="tabpanel" class="tab-pane" id="settings">...</div>
</div>

通常最好将内容分组，但看起来 div 没有添加 class 真的没关系。

Is there any advantage in having the nav tabs and tab panes in the same div?
