CSS Working Group
The CSS Working Group (Cascading Style Sheets Working Group) is a working group created by the World Wide Web Consortium (W3C) in 1997, to tackle issues that had not been addressed with CSS level 1. The number of members reaches 125 in April 2017.

The first CSS test suite (CSS1) was created by Eric A. Meyer, Håkon Wium Lie and Tim Boland along with other contributors. In early 1996 Lie cooperated with Bert Bos, who was already developing a new browser language called SPP, and produced CSS standard. They presented their achievements twice in 1994 and in 1996 at the "Mosaic and the Web" conferences in Chicago. W3C was being established by that time and Lie's and Bos's work caught their attention.
- "CSS level 1 finally emerged as a W3C Recommendation in December 1996."
- The same group working on CSS was also developing HTML and DOM. This group, HTML Editorial Review Board, in 1997 was divided according to the three different programs.
- Chris Lilley managed the CSS working group, which in February 1997 started working inside W3C, deal with the issues uncovered by the CSS1.
- In late 1998 the CSS level 2 was released, while it was revised in 1999.
- By 1999 there are 15 members working in "Cascading Style Sheets and Formatting Properties Working Group."
- The construction of the third level of CSS started in 1999, but until 2006 it faced serious limitations.
- In 2005 the CSS Working Group decided that already published standards (CSS 2.1, CSS3 text etc.) should be re-examined and updated.
Benefits for members
CSS working group members belong to the broader organization W3C. This membership offers to them four important benefits; interaction, strategy, participation and leadership. The first characteristic provided, can be explained more as an opportunity to meet and work with “leading companies, organizations, and individuals” specialized in web technologies. “W3C Activity proposals” are strategically examined and operated by the members, giving them the ability to work methodically. Participating in the CSS working group allows members to change/shape technologies influencing businesses as well as consumers. Finally, CSS members are adopting a significant role into the W3C project of developing the Web standards, which requires leadership skills and dedication.
