In this chapter, we described the Foundation CSS/JavaScript framework. It allows us to create a mobile first, responsive design site or application without having to write any code for the responsive part. We only have to customize it to our needs.

This concludes the part of the book that covers what I would like to call modern web development. In the final chapter, we advance to what most of us will seem avant garde, although by the time this book is printed, it will be very much en vogue. And it is all built around a JavaScript thing that is not written in JavaScript called node.js.
