Abstract:

Web style sheets have been around for a number of years, but their power and importance went largely unnoticed since few implementations existed. Web authors, anxious to add creativity to their pages by influencing the presentation, began to use Netscape's proprietary extensions rather than the more powerful style sheets. This was quite natural, since Netscape's proprietary extensions could be seen by a significant portion of Web users, while few would see style sheet enhancements.
