CSS3实现立体菜单

html结构：

<div class="nav">
        <a href="#" class="highlight">Home</a>
        <a href="#">About</a>
        <a href="#">Servics</a>
        <a href="#">Portfolio</a>
        <a href="#">Blog</a>
        <a href="#">Contact</a>
    </div>

CSS3：

* {
            margin:0;
            padding: 0;
            font-family: 'Microsoft Yahei'
        }
        a {
            color: #fff;
            text-decoration: none;
        }
        body {
            background-color: #222930;
        }
        .nav {
            margin:10%;
        }
        .nav a {
            padding: 15px 20px;
            margin-left: -4px;
            border: 1px solid #121212;
            border-right: none;
            color: #777;
            cursor: pointer;
            font-size: 14px;
            box-shadow: 0 2px 3px rgba(255,255,255,0.1) inset,
