www.targetcw.com was redeveloped by me in Drupal 7. I used jQuery to create the fun animations. To make the site responsive, I used css media queries along with jQuery to detect screen size and other device features.   Each page that has javascript navigation has a javascript router I wrote to load the appropriate content according to the appended URL. 

Check out these URLs for the animations
