Cool CSS3 navigation menu

The HTML

The markup could not be simpler and includes also the new HTML5 nav element.

<nav>

   <ul>

       <li><a href="">Home</a></li>

       <li><a href="">Categories</a></li>

       <li><a href="">About</a></li>

       <li><a href="">Portfolio</a></li>

       <li><a href="">Contact</a></li>

   </ul>

</nav>

 

The CSS

The CSS lines below are easy to understand and I think there isn’t too much to explain:

nav  {

        display: block;

        width: 100%;

        overflow: hidden;

}



nav ul {

        margin: 80px 0 20px 0;

        padding: .7em;

        float: left;

        list-style: none;

        background: #444;

        background: rgba(0,0,0,.2);

        -moz-border-radius: .5em;

        -webkit-border-radius: .5em;

        border-radius: .5em;

        -moz-box-shadow: 0 1px 0 rgba(255,255,255,.2), 0 2px 1px rgba(0,0,0,.8) inset;

        -webkit-box-shadow: 0 1px 0 rgba(255,255,255,.2), 0 2px 1px rgba(0,0,0,.8) inset;

        box-shadow: 0 1px 0 rgba(255,255,255,.2), 0 2px 1px rgba(0,0,0,.8) inset;

}

}

 }

        outline: 0;

        color: #fff;

        -webkit-border-radius: 4px 0 0 4px;

        border-radius: 4px 0 0 4px;

        -webkit-border-radius: 0 4px 4px 0;

        border-radius: 0 4px 4px 0;
