HTML (or Hyper Text Markup Language) is prehaps the most volatile resource that is involved. A key feature of the World Wide Web, the details of HTML's functionality, and the clients which interpret it, determine the look, feel and limitations of Web resources. While HTML v2.0 is the current standard, having replaced v1.0 only months ago, and is largely responsible for the popularity of the Web (thanks to in-line images, audio and certain formatting features), its limits have been the source of constant frustration for many developers. This is so much so that Netscape Communications, makers of the most popular browser Netscape Navigator, almost immediately introduced ``extensions" to HTML which have subsequently caused many problems; many Web designers use the extensions (such as tables, background colours, and server/client push/pull) resulting in pages that can only be properly viewed by Netscape.
