如何設計導航標簽

Question

我正在嘗試創建類似箭頭形狀的導航標簽。

誰能告訴我哪個CSS屬性將適用於獲得此形狀。

<ul class="nav nav-tabs">
   <li><a href="#a" data-toggle="tab">home</a></li>
   <li><a href="#b" data-toggle="tab">contact</a></li>
   <li><a href="#c" data-toggle="tab">network</a></li>
   <li><a href="#d" data-toggle="tab">adress</a></li>
</ul>
<div class="tab-content">
   <div class="tab-pane active" id="a">AAA</div>
   <div class="tab-pane" id="b">BBB</div>
   <div class="tab-pane" id="c">CCC</div>
   <div class="tab-pane" id="d">DDD</div>
</div>
