The book is very upfront about the spotty early browser support for CSS1 and the sluggish adoption of CSS2. However, enthusiasm for the technology spills out of the pages, making a strong case for even the most skeptical reader to give CSS a whirl and count on its future. The text covers CSS1 in impressive depth--not only the syntactical conventions but also more general concepts such as specificity and inheritance. Frequent warnings and tips alert the reader to browser-compatibility pitfalls.

Entire chapters are devoted to topics like units and values, visual formatting and positioning, and the usual text, fonts, and colors. This attention to both detail and architecture helps readers build a well-rounded knowledge of CSS and equips readers for a future of real-world debugging. Cascading Style Sheets honestly explains the reasons for avoiding an in-depth discussion of the still immature CSS2, but covers the general changes over CSS1 in a brief chapter near the end of the book.

When successfully implemented, Cascading Style Sheets result in much more elegant HTML that separates form from function. This fine guide delivers on its promise as an indispensable tool for CSS coders. --Stephen W. Plain

Particularly for developers, CSS allows more precise control of elements inside browsers, making it a lot easier to create Web clients that compete with traditional stand-alone applications. But support for CSS in today's browsers is spotty. The strength of this book is that it explains both the CSS1 and CSS2 standards, even though they are still under development. This text shows off what each property is supposed to accomplish with sample HTML and screenshots. The author is careful to note problems with CSS properties in today's browsers. For the CSS1 standard, every property is marked as being unsafe, safe, or partially implemented on no less than eight browsers (including Netscape 3 and 4.x, Internet Explorer 3 through 5, and Opera for Windows, UNIX, and Mac platforms).

The second part of the book is devoted to the CSS2 standard with a description of proposed support for Unicode, for formatting Web pages (with paged media properties), and for tagging content so that it can be read out loud by computer-generated voices. Although still under construction, the CSS1 and CSS2 standards will certainly offer a better Internet for us all. In the meantime, Core CSS: Cascading Style Sheets describes what's available in today's browsers. It's a solid reference that will make CSS understandable to anyone, regardless of their level of Web expertise. --Richard Dragan
