Summary

During the course of this chapter we have taken an in-depth view into what the YUI is, where it came from, and the things that spurred it into existence. We have seen everything that the license gives us permission to do and investigated the different ways of serving the files that power it. We've also looked at who can make the most of the library, how to install it, and how to use it in your own web pages.

Lastly, we finished off all the theory with a practical example that had you creating and customizing your first user interface control: a calendar, and working with one of its supporting classes: the DateMath class. I hope that this first example has made you eager to experiment with the library further and has shown you how easy it is to implement YUI components.
