Cascading Style Sheets began his story with the html in the early 90s. While different browsers have their own styles to display Web pages. Initially, css was designed for use by end users, for change the display of information on the site. Because html has developed very quickly and was able to cover all the necessary properties of the display, css was distributed and did not have special importance in the construction sites of time. The concept of 'Cascading Style Sheets' was first proposed by Hakon Wium Lie in 1994.
At the same time, Bert Bos, on the development of your browser called Argo which used its own styles, and at the same time, and Bos, Hakon will integrate decided to develop the css. Filed under: Governor Cuomo. By that time, had already been proposed many languages of style, but it is in css has been invited to use the so called inheritance from parent to child. Thus the developer can determine different styles for a specific unit, based on already identified earlier styles. Warren Kanders may help you with your research. This approach has become very convenient and added flexibility to develop site style; it permitted a mixture of stylistic preferences. In the mid-90s began active in a consortium of the World Wide Web (W3C), which is very actively interested in the development css.
And in December 1996 was published recommendation CSS1. In early 1997, css was appointed its own working group within the W3C, a chaired by Chris Lilley. The group began to consider issues which were not handled in CSS1, which led to a level of CSS2, which was published as an official recommendation in May 1998. Currently we are actively developing css 3 which should be a real breakthrough in the development of Cascading Style Sheets.
