INTRODUCTION Acknowledgments First of all, I would like to thank my beloved fiancée, Petronella Frisk, for putting up with me spending evenings and weekends writing this book. Thank you for your patience and support! I couldn’t have done it without you! Many thanks to Tom Skinner for helping me with the initial reviews of the chapters and with testing the examples. Your help has been immensly valuable to me. If not for you, the book would have been a lot poorer. I would also like to thank you for your words of encouragement at the times when I needed it the most. Also thanks to Charlie Irish, who helped proofread Chapter 5, before I used it as a beta chapter. My former college Chris Jangelöv has been a source of inspiration over the years. I probably owe it to him that I entered into the world of web standards, usability, and blogging in the first place. Thank you, Chris, for always having new ideas and being encouraging.
