CSS (Cascading Style Sheets) is the W3C-approved method for enriching the visual presentation of web pages. CSS allows web pages to become more structural, and at the same time promises that they can have a more sophisticated look than ever before. With good implementations in Internet Explorer 5.0 and Opera 3.6, and 100% CSS1 support expected in Netscapes's Mozilla browser, signs are that CSS is rapidly becoming a useful, reliable, and powerful tool for web authors.
The CSS Pocket Reference briefly introduces CSS and then lists all CSS1 properties, plus the CSS1 pseudo-elements and pseudo-classes. Since browser incompatibility is the biggest obstacle to CSS adoption, we've also included a comprehensive guide to how the browsers have implemented support for CSS1. For anyone who wants to correctly implement CSS, this is a handy condensed reference to all the details in the larger volume, Cascading Style Sheets: The Definitive Guide.
