Welcome to Instant Fancybox. The goal of this book is to teach you how to install, use, and customize the Fancybox plugin for jQuery. This book discusses in detail the second version of the Fancybox plugin. The first version will not be covered because Fancybox2 is much more rich in features and is more powerful than its predecessor, and I strongly suggest using it or switching to it! This book assumes that the reader has some basic understanding of web development including knowledge of HTML, CSS, and very basic JavaScript.
