What is HTML?
HTML, or HyperText Markup Language, is a markup language derived from SGML, used to describe web sites and applications to be run in a common web browser. Invented in 1993 by Sir Tim Berners-Lee, HTML documents are broken up into HTML elements, which describe the component parts of the document. HTML attempts to provide a means for defining the structure of the data in a document, while also giving control over the presentation of the document. Starting in 1996, CSS was developed as an adjunct to HTML in order to better separate the presentation of a document. This is meant to allow documents to be written in a way that more clearly and accurately reflects the structure of the information, without being distorted by presentational needs. Today, CSS and HTML are almost always used in conjunction.
