The History of HTML

Hypertext Markup Language or commonly abbreviated "HTML is a markup language for creating a site. In 1989-1990, a computer scientist Tim Berners-Lee invented the Worl Wide Web. HTML is one of three inventions from the WWW with the Hypertext Transfer Protocol (HTTP) and web addresses. The first version of HTML includes the document title, the structure of text titles, subheadings, lists, or plain text, hyperlinks, but also a principle of optimization. Tim Berners Lee based on the HTML SGML (Standard Generalized Markup Language) is a language standard generalized markup to attract business in the html.

In late 1993, the HTML which is then has seen a version of a normalizing effect. It is now called HTML +. Unfortunately, until the late 1990s, the html is defined by implementations of browsers. The arrival of the NCSA Mosaic browser brings two major elements: the insertion of images and the introduction of forms.

On November 13, 1993, the emergence of the new Netscape Navigator 0.9 allows the addition of many elements: text attributes, etc. centering. Now the html and browsers take into account the design and even expand its capabilities especially with CSS. The protocol describing HTML 2.0 is finalized by the end of 1995. It describes the HTML before June 1994, ie without the many updates due to the browser Netscape Navigator 0.9. Dan Conelly is the principal author of this document.

In December 1997 the W3C (World Wide Web Consortium) founded by Tim Berners-Lee in 1994 published the HTML4.0. The main novelties are the remarkable separation between structure and presentation of the document but also the standardization of design elements and scripts. Other elements are added framset particular tag, transitional or strict. In the 2000s, computer scientists prefer to tackle the XHTML and HTML forget. Only in March 2007 that the W3C decided to relaunch the development of HTML, with the head of research Chris Wilson (Microsoft).

The History of CSS

CSS (Cascading Style Sheets: Cascading Style Sheets) is a computer language that allows the formatting of a web page. Created by the W3C in the 1990s, it is fully supported by browsers in the 2000s. The first real proposal style sheets proposed by Hakon Wium Lie. Soon, Dave Raggett is then the principal editor of the draft specification HTML3 publishes a document referring to the work of Hakon Wium Lie. The final specification is published CSS1 December 17, 1996. The first version of CSS does not allow a layout but only a "formatting style (font, color, character ...).

In 1997, the study of CSS is handled by a team chaired by Chris Lilley W3C. This group contains representatives of most major browsers.

In May 1998 the second version of CSS, with 70 new properties appear. Problems of implementation of the W3C CSS lead out in 2001 a revised version of the CSS2. The development of CSS3 starts in 1999. But development is very difficult with the problems of updating and implementation. The evolution of CSS is constant and it took over 10 years to finalize its version 3.
