Acknowledgments

Creating a lasting specification for the Web is not a job for one person. That's why the two authors joined forces. Then, we found out two wasn't enough, and a W3C Working Group (which includes W3C technical staff and W3C member representatives) was formed. The CSS 2.1 specification is the product of that working group. We are indebted to Tantek Çelik and Ian Hickson, who are co-editors of the CSS 2.1 specification, and to the other members of the group. In particular, we want to thank David Baron, Jim Bigelow, Kimberly Blessing, Frederick Boland, Ada Chan, Don Day, Michael Day, Elika Etemad, Daniel Glazman, David Hyatt, Björn Höhrmann, and Kevin Lawver.

CSS 2.1 is only the most recent version of the CSS specification. The foundation for CSS was laid by CSS1 and CSS2, and many people helped write, maintain, and promote those documents. In roughly chronological order:

• David Raggett and Steven Pemberton were influential in establishing the concept of style sheets for the Web.

• Eric Meyer created the test suite for the CSS1 specification and has promoted CSS tirelessly ever since.

• Todd Fahrner created the W3C Core Styles (described in Chapter 14), the "acid" test, and the Ahem font.

• Ian Jacobs and Chris Lilley were co-editors of the CSS2 specification.

• Brian Wilson provided extensive documentation of CSS and its implementations.

• Jeffrey Zeldman has publicized widely on why standards, including CSS, are good for you.

• Dave Shea created the wonderful CSS Zen Garden.

• Michael Day and Xuehong Liu for making it possible to print CSS. Thanks to the Prince formatter, we were able to produce the book ourselves using the same methods we preach in this book.

Lastly, our thanks to Tim Berners-Lee, without whom none of this would have been possible.
