如何设计导航标签

Question

我正在尝试创建箭头形状的导航标签。

任何人都可以告诉我哪种css属性适用于这种形状。

<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>
