In 1994 he worked on Delrina's Cyberjack Web browser and on its accompanying Web site, one of the first commercial Web sites. His long-running series on HTML, Weaving Your Own Web Site was drawn from his professional experience, and ran monthly for almost just over 90 issues in The Computer Paper Publication. Many of the early issues in this series were pulled together to form the core of his first book The Advanced HTML Companion in 1997.

Since then several other books have followed. His interest in CSS began while writing his second book on HTML in 1998, when he realized that there were no good references on the subject. So he decided to write one.

Between 1996 and 1999 Schengili-Roberts was in a Kingston, Ontario indie band called "Miscellaneous 'S'".
