目前我有一个看起来像这样的div:

我需要编辑HTML/CSS,使其显示如下,下面有一个小三角形.理想情况下,我想使用纯HTML和CSS,没有图像文件.根据CSS-Tricks,它可以完成.

HTML:

<ul id="nav">
    <li class="active"><a href="#"><div class="triangle"></div>Dashboard</a></li>
    <li><a href="users/index.html"><div class="triangle"></div>Manage Users</a></li>
    <li><a href="tickets/index.html"><div class="triangle"></div>Manage Tickets</a></li>
    <li><a href="reports/index.html"><div class="triangle"></div>Reports</a></li>
</ul>

CSS:

#nav {
    float: right;
    margin: 0;
    padding: 8px 0 0 0;
    list-style: none;
    display: inline-block;
}

#nav li {
    float: left;
    padding: 7px 5px;
    margin: 0 5px;
    font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; 
    font-weight: 300;
    border-radius: 7px;
}

#nav li a {
    color: #0b70cc;
    text-decoration: none;
    padding: 7px 5px;
} …
