// Title : Dynamic Resolution Dependent Layout Demo
// Author : Kevin Hale
// URL : http://particletree.com
//
// Description : This is a demonstration of a dynamic 
// resolution dependent layout in action. Change your browser 
// window size to see the layout respond to your changes. To 
// preserve the separation of the presentation and behavior 
// layers, this implementation delegates all the presentation 
// details to external CSS stylesheets instead of changing 
// each style property through JavaScript.
