The framework provides fully functional widgets and controls right out of the box which know how to behave so you can focus only on providing the data.

A new concept is introduced by the framework: WAML (Web App Markup Language) which is designed for creating mobile web apps and uses special tags + attributes to clearly define all the parts (rather than divs and spans) for a faster development.

ChocolateChip-UI has most of the elements we get used from iOS like the buttons, tab bar, lists, slider and more.

The framework is very well-documented, provides snippets for the basics and definitely a must-bookmark for mobile web app development.

PhantomJS is a command-line tool that acts like a WebKit browser without any interface.
