基于Flexbox与jQuery的轻量级Tab选项卡实现

<div class="m-tab-container">
  <ul >
    <li class="active"><a href="#pane1">面板1</a></li>
    <li><a href="#pane2" rel="external nofollow" >面板2</a></li>
  </ul>
  <div>
    <div id="pane1" class="active">
      这是面板1
    </div>
    <div id="pane2">
      这是面板2
    </div>
  </div>
</div>
