This chapter has the longest title in the book, fitting for the most important one. In it, we explained the difference between web development yesterday and web development tomorrow. We explained that you need to think mobile first, that your design has to be responsive, and that you should reward customers who have the latest, greatest stuff by using the cool new features through progressive enhancement.

In the next chapters, we will guide you through how to apply all that came before using a cool CSS/JavaScript framework, Foundation, so you can use what someone already did for you. We will also show you a way to take full control of how you want things to be handled on the server side, using node.js.

If you stop right here, you have learned the basics of modern web development and I congratulate you for doing that. If you go on, you will learn to use a framework that will save you a lot of time and work in the long run as well as what looks like a totally different way of doing things...
