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 403 on October 2014.〔()〕 The working group is co-chaired by Daniel Glazman and Peter Linss. ==CSS Working Group History== The first CSS test suit (CSS1) was created by Eric A. Meyer, Håkon Wium Lie and Tim Boland along with other contributors.〔http://www.w3.org/Style/CSS/Test/CSS1/current/tsack.html〕 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.〔(Nicolae. Web Design & Development: Nicolae Sfetcu, 2014.
