Chapter 4 – Cascading Style Sheets Basics
Web designers use CSS to separate the presentation style of a web page from the information on the web page. CSS can configure text, color, and page layout.
CSS first became a W3C Recommendation in 1996. Additional properties for positioning web page elements were introduced to the language with CSS level 2 (CSS2) in 1998 but did not reach official Recommendation status until 2011.
