CSS stands for cascading style sheets. It is a programming language that is used to describe how a Web Page looks from colour, to fonts and layout.
CSS is a style sheet language that allows coders to add styles to web documents written in HTML or XML.
These styles include things like font types, letters colours or spacing between characters. The syntax used in CSS all derivates from simple English words such as id, class, bold, italic, space, etc.
CSS can also control the layout of multiple web pages all at once.
CSS was originally released in December 1996 by the World Wide Web Consortium (W3C) and Håkon Wium Lie and Bert Bos.
What version of CSS should you use?
Throughout the years, different variations of cascading style sheets have been released.
The first variation, CSS 1 was introduced in 1996 when it became an official W3C Recommendation.
