The jQBoxModel plugin is a plugin for jQuery that allows you to quickly prototype complex layouts.

This plugin was developed to streamline the page layout process by using % widths to have your main content width take up a percentage of the parent width then have sibling widths automatically calculated to take up the remaining space among themselves.

The demo also highlights the use of CSS3 Media Queries to dynamically serve different layout based on the screen width (resize the browser to see it in action).
