The Centaur Demos

The Centaur demos are used to demonstrate the power and the flexibility of the CGIDEV2 WEB development method authored by Mel Rothman.
(Please note that CGIDEV2 is a prerequisite for installing these demos.)

The Centaur demos are not for newbies.
Though they may look attractive, to be understood they imply some familiarity with Mel Rothman's CGI development method.
This is why we do not recommend them as a first step in learning Mel Rothman's method.
If you are a beginner, you've better follow the learning pattern in page Tips for CGIDEV2 initial learning.

There are two Centaur demos:

  •   This is the original demo, designed for full pages.
    It implements Responsive HTML, a HTML method that allows to automatically resize, hide, shrink, or enlarge, a website,
    to make it look good on all devices (desktops, tablets, and phones).
    Read about it on W3Schools.
  •   This second demo was designed to run in frames, this providing a better presentation, though this approach implies further complexities.
    Some JavaScript had to be added to synchronize the frames. Besides, debugging CGI programs in frames is not all of the times easy.

Please note that, to inhibit the back button on the browser (such button, if used while entering an order, may cause extra items been added to the order), we open a new window without the toolbar.
This is done through JavaScript function openWin in this page.

You could also remove the location information, thus even more shielding your web application, as it is done through JavaScript function openWinNoloc in this page.
