The Creators of CSS

Bert Bos and Håkon Wium Lie are renowned for their collaboration in the development of Cascading Style Sheets (CSS), a cornerstone technology of the web. Here’s a brief overview of their collaboration and its impact:

Håkon Wium Lie proposed the concept of Cascading Style Sheets (CSS) in 1994 while working at CERN. He was motivated by the need for web documents to be presented in different styles and layouts without compromising their structure and accessibility.
Bert Bos, a researcher and developer, created his own style sheet language called Argo. His work caught the attention of Wium Lie and others in the web standards community.

  • Recognizing the potential in each other’s work, Bos and Lie collaborated to merge their ideas, which helped in shaping the early development of CSS. This collaboration was crucial as it combined Bos’ technical prowess with Lie’s visionary approach.
  • They worked together to refine CSS, advocating for it as a standard through the World Wide Web Consortium (W3C), where they both contributed significantly to the development of CSS Level 1.
