Abstract

We describe and evaluate Cobweb, which we believe is the first web page renderer based on constraint-solving technology. One-way constraints are used to specify position and style attributes of the document elements. Our implementation demonstrates how constraint solving provides a unifying technology for the rendering of web pages. It also demonstrates that constraint solving inherently supports viewer interaction with the document and that constraints allows more flexible and powerful specification of document layout, in particular complex text-flow, than is available with existing technologies.
