CSS Introduction tutorials
-
CSS, stands for Cascading Style Sheets, is used to style and control
the layout of WebPages. This language is used to define the presentation of
HTML elements on a webpage. CSS can be used to define colors, fonts, borders,
and the layout of a webpage.
-
CSS is simple mechanism for adding Style i.e. fonts, colors, spaces to web
elements.
-
CSS is a style sheet language used for describing the presentation
semantics (the look and formatting) of a document written in a markup language.
-
CSS is syntax used in the markup languages HTML and XHTML and has limited
use in XML documents. HTML and XHTML are the programming languages most widely
used and they are supported by most search engines. CSS is used in almost every
aspect of today’s website designs.
-
Since the beginning of style sheet usage in the 1970’s, it has evolved
through wide-spread study and testing. It wasn’t until the mid-1990’s that CSS
was introduced to the World Wide Web Consortium (W3C).
-
At that time, W3C members became involved in its development, as well. In
the late 1990’s, CSS was ready to go LIVE and in December 1996, the syntax
became official. Even with the tremendous support from the W3C, Internet
Explorer 3 was released in 1996 with very little support for the highly useful
style sheet syntax.
-
Three years later, Internet Explorer 5 was released and had a nearly 100%
compatibility and support for CSS.
-
Introducing different variations of CSS, such as CSS1, CSS2 and CSS3, aided
in weeding out the properties that browsers simply wouldn’t support.
-
Creating a standard for CSS and browser compatibility was mandatory for a
successful syntax and style tool. By using variations from all forms of CSS,
CSS2.1 was created in late July 2007. However, since changes and clarifications
were made, it again went back to Last Call Working Draft on 7 December 2010.
-
CSS 2.1 went to Proposed Recommendation on 12 April 2011.After being
reviewed by the W3C Advisory Committee; it was finally published as a W3C
Recommendation on 7 June 2011.
-
CSS 3 is divided into several separate documents called
"modules". Each module adds new capabilities or extends features
defined in CSS 2, over preserving backward compatibility. Work on CSS
level 3 started around the time of publication of the original CSS 2
recommendation.
