My client wanted to make a transition between pages. I thought it would be difficult to do, but with help of Scriptaculous effects and Prototype's $$() function it turned out to be pretty simple.
The method I used is easy to use, unobtrusive and needs only one element which usually is already in the code – main div surrounding all page content.
The picture above shows Safari, Internet Explorer, Firefox and Windows panel within VMware Server and Gnome and Opera within Linux. Now it's simple. Thank you Apple.
