can you check effect on next link:
... when you click on "what is...", "why use..." and "how does..."
it there simular one for joomla and drupal cms's?
thank you in advance!
This doesn't has anything to do with the used CMS, but with the used template (which itself uses some kind of JS-library - in the case of modxcms.com its jQuery).
i also guess that it's jquery, but which effect?
