Riocar.org runs on PHPNuke, which is a server-side scripting language.

At the bottom of each of the Riocar pages are three icons which link you to the necessary software. In this case, Apache (the web server), PHP (the scripting language), and PHPNuke (the site-builder software based on PHP).

This allows you to mix HTML with the convenient server-side coding of PHP.
