Lo único que pude ver de esa web tan buena es un texto que dice...
Cita: Currently this site uses DHTML as implemented in Netscape 4.x and Explorer 4/5.x under the Windows platform. The next version of this site is being built upon full DOM, HTML, CSS and XML standards set forth by the W3 and fully implemented by the Mozilla project and hopefully be supported by all platforms. Stay tuned for the next version coming soon, it will be an experience!
