I have a CSS menu using the following CSS.

What is the best way to center the whole menu on the page?

I have tried using another `<div>` outside `<nav>` and setting margins but its just aligning left all the time.

```
nav {
    margin: 0 auto; 
    text-align: center;
    border:1px solid black;
}

nav ul ul {
    display: none;
}

nav ul li:hover > ul {
    display: block;
}

nav ul {
    list-style: none;
}

nav ul li {
    float: left;
}

nav ul li:hover a {
    color: #000000;
}

nav ul li a {
    display: block; 
    padding: 10px 15px;
    color: #000000;
    text-decoration: none;
}       

nav ul ul {
    border-radius: 0px;
    padding: 0;
    position: absolute;
}

nav ul ul li {
    float: none; 
    border-top: 1px solid #000000;
    border-bottom: 1px solid #000000;
    position: relative;
}

nav ul ul li a {
    color: #000000;
}

nav ul ul li a:hover {
    color: #666666;
}

nav ul ul ul {
    position: absolute;
    top:0;
}

```
