HÃ¥kon Wium Lie is a web pioneer, standards activist, and as of 2010, Chief Technology Officer of Opera Software.
He is best known for proposing the concept of Cascading Style Sheets (CSS) while working with Tim Berners-Lee and Robert Cailliau at CERN in 1994.
As an employee at W3C, he developed CSS into a W3C Recommendation with Bert Bos.
Along with his work on the CSS specifications, Wium Lie has been an activist for standards in general.
Often, Microsoft's Internet Explorer has been his target due to its poor support for standards. Also, he has argued against the use of formatting objects on the web.
Wium Lie has also promoted the concept of printing from the web. His book on CSS, co-authored with Bert Bos, was produced from HTML and CSS files. These files were then converted to PDF by the Prince XML formatter.
