Here I give credit where credit is due for the libraries used to make this website.
Google Material Design Lite
The layout, navigation and many of the visual components of this website are designed using Google's Material Design Lite, a wonderful framework for designing websites.
I use Docpad now to maintain this website. It is an excellent tool for building and maintaining static websites using Node.JS and many other Node-based libraries.
I use Stylus to manage all of the custom CSS for this website.
I use eco (Embedded CoffeeScript) as a templating engine for this website.
The demo apps & games section of this site use Bootstrap, not just for the layout, but much of the UI for the games is designed using Bootstrap components.
