One of the most potentially harmful obstacles to future interoperability on the Internet has been overcome with the World Wide Web Consortium announcing that its members have agreed to develop a common way of integrating style sheets into hypertext documents. At present, content providers do not have control over colour, text indentation, positioning and other style aspects. The style sheet work will be based on Hakon Lie’s Cascading Style Sheets initiative at INRIA Sophia Antipolis. The Cascading Style Sheets mechanism will enable authors and readers to influence the presentation of HyperText Mark-Up Language documents by inserting their preferred style sheets, and will offer better support for printing HyperText Mark-up Language documents.
