In 1990, Tim Berners-Lee and Robert Cailliau invented the Web. In 1994, the Web really came out of the lab. [3]

Styles have existed in various forms since HTML was invented. Different browsers combine their style languages to give the user control over how the page looks. The original HTML contained very few display attributes.

As HTML has grown, many display capabilities have been added to meet the needs of page designers. But as these capabilities increased, HTML became more cluttered, and HTML pages became more bloated. CSS was born.

The original proposal for CSS was made by Hakon Leigh in 1994. Bert Bos was designing a browser called Argo, and they decided to design CSS together.

There were already suggestions for a unified stylesheet language, but CSS was the first stylesheet language with the word "cascading" in it. In CSS, the style of a file can be inherited from other stylesheets. The reader can use his own preferred style in some places, and inherit or "cascade" the author's style in others. This layered approach gives both authors and readers the flexibility to add their own designs, blending everyone's tastes.

Hakun first proposed CSS at a conference in Chicago in 1994, and again at the 1995 WWW Web conference, where Boss demonstrated examples of CSS support for the Argo browser, and Haken showed the Arena browser with CSS support.

In the same year, the World WideWeb Consortium (W3C) was established, and all CSS creators became W3C working groups and devoted themselves to developing CSS standards, and the development of cascading style sheets finally got on the right track. More and more members got involved, such as Microsoft's Thomas Reaxdon, whose efforts eventually led to Support for THE CSS standard in Internet Explorer. Hakun, Bos and others are the main technical leaders on the project. By the end of 1996, the first draft of CSS was complete, and in December of that year, the first formal standard for Cascading Style Sheets (Cascading Style Sheets Level 1) was completed as a W3C recommendation.

In early 1997, a W3C working group on CSS began discussing issues not covered in the first release. The results of this discussion formed the second edition of the CSS specification, published in May 1998. [4-5]
