功能区样式菜单？

Question

我有一个简单的问题，谁能帮我把我的菜单看起来像这个网站上的那样：

我现在尝试了几件事，但似乎无法得到它......

我当前的代码是：

HTML：

<div class="navbar">
    <ul>
        <li><a href="index.html">HOME</a></li>
        <li><a href="#">TREATMENTS</a></li>
        <li><a href="#">CONTACT</a></li>
        <li><a href="#">OTHER</a></li>
    </ul>
</div>

CSS：

/*Content for Navigation Bar*/
.navbar {
    width: 760px;
    padding-left: 200px;
    height: 50px;
    background-color: #534b49;
    text-align: center;
    float: left;
    font-size: 20px;
    padding-top: 0px;
    padding-bottom: 0px;
}
.navbar ul {
}
.navbar ul li {
    list-style: none;
    text-align: left;
}
.navbar li {
    float: left;
    padding-right: 15px;
}
.navbar li a {
    color: #fff;
    text-decoration: none;
}
.navbar li a:hover {
    color: #00a6bd;
    text-decoration: none;
}
.navbar li a#active {
    color: #00a6bd;
    text-decoration:none;
}

提前致谢！
