Terrific is an Open Source project that comes in two flavours:
TerrificJS is a neat, clever piece of code that allows you to modularize your jQuery code by solely relying on the OOCSS naming conventions.
So simple, so effective! TerrificJS helps you to structure your project in a way you have never dreamt of. Try the magic and get addicted.
Terrific melts TerrificJS, OOCSS and hundreds of best practices.
The result is a frontend development framework that is extremely powerful and intuitive to use. You will never miss it again!
Terrific is coming soon and will be released as a bundle for Symfony2.
