IIS 7.0 not serving CSS files

After a rebuild of IIS 7, I couldn't get any CSS files to return. If I browsed to the path http://localhost/styles.css, I would a blank page (even when I view source). The problem was that during the reinstall of IIS I forgot to add the Static Content Component.

For Vista and Windows 7:
Control Panel -> Programs -> Turn Windows features on or off

Then navigate to: Internet Information Services -> World Wide Web Services -> Common HTTP Features
Enable the Static Content option
