In desktop publishing, a style sheet makes it possible to effect a "global" change within a document. On the World Wide Web, cascading style sheets will make it possible to make similar global changes, but in a set of widely distributed HTML documents that may reside in servers literally around the world. This book describes the special opportunities and challenges for designers who want to understand this emerging Web function as it is being developed by the W3 Consortium. Details on how the standard is emerging, as well as its implementation in Microsoft and Netscape browsers, will be covered in detail, along with management, security, and design considerations that Webmasters are likely to face.
