Craigslist - Structural
While this project doesn't change much of the face of Craigslist, it illustrates how to set up a project including mappings, page-specific styling, and spriting of images.
You can follow along with how this project is generated on the complex site transformation tutorial.
This project works with Moovweb's development framework. To get it running, navigate to the folder in your command line and start the server with the command:
