From the site:

“Welcome to Webmaker — a Mozilla project dedicated to helping you create something amazing on the web. Our tools, events and teaching guides allow webmakers to not only create the content that makes the web great, but — perhaps more importantly — understand how the web works. With this knowledge, we can make a web without limits. That’s the philosophy behind webmaker.org. We’ve built everything so you can see how it works, take it apart and remix it. Enjoy!”
