What is CSS?
CSS stands for Cascading Style Sheets
Styles define how to display (X)HTML elements
Styles are normally stored in Style Sheets
Multiple style definitions will cascade into one
A Brief History of CSS
Style sheets have existed since the beginnings of SGML in the 1970s
As HTML grew, it came to encompass a wider variety of stylistic capabilities
Nine different style sheet languages were proposed to the W3C
Two were chosen as the foundation for CSS: CHSS and Stream-based Style Sheet Proposal
CSS level 1 – 1996; CSS level 2 – 1997
Difficulties with adoption
