html - Alternate background colors for list items

Question

I have a list, and each item is linked, is there a way I can alternate the background colors for each item?

<ul>
    <li><a href="link">Link 1</a></li>
    <li><a href="link">Link 2</a></li>
    <li><a href="link">Link 3</a></li>
    <li><a href="link">Link 4</a></li>
    <li><a href="link">Link 5</a></li>
</ul>

How about some lovely CSS3?

li { background: green; }
li:nth-child(odd) { background: red; }
