HTML

 Hypertext Markup Language (HTML), is a markup language used to create and design web pages and websites, and this language is considered one of the oldest and most widely used languages ​​in web page design. HTML Structure of a web page Gives the Internet browser a description of how it displays its contents Techniques such as Cascading Style Sheets (CSS) and scripting languages ​​such as JavaScript Web browsers receive HTML documents from a web server or file system and display them, and the function of HTML is to describe the structure of pages The web is structural.

Elements in HTML are the basic building blocks of HTML documents, with which we can add images and interactive objects such as forms or video and audio files; You can also create structured documents by using tags to denote paragraphs, headings, links, quotes, tables, and more.

HTML can include programs written in languages ​​such as JavaScript to modify the behavior and content of web pages; Adding CSS code defines the look and layout of the content.

History of HTML

In the 1980s, physicist Tim Berners-Lee, who was an employee at CERN, proposed and prototyped a system that would enable CERN researchers to use and share documents. In 1989 he wrote a memo proposing an Internet-based hypertext system, describing HTML and writing server and browser programs in the late 1990s.

The first public description of HTML was a document called HTML tags first mentioned on the Internet by Berners-Lee in late 1991. It describes 18 of the first components that comprise it, and the design is relatively simple in HTML with the exception of This hyperlink tag, strongly influenced by SGML QUID, is based on SGML as documents at CERN's home. Eleven of these elements are still present in HTML.

Hypertext Markup Language is a markup language that web browsers use to interpret and compose text, images, and other material in audio-visual web pages. The default properties of each HTML element are defined and coded in the browser, and these properties can be changed or improved by using an additional ASS web page designer. Several elements of text are found in a 1988 (ISO) Technical Report (TR9537) Techniques for Use (SGML) which in turn covers features of early text format languages ​​such as those used by the runoff command developed in Early 1960s for CTSS (Compatible Time Sharing System) operating system: These formatting commands were derived from the commands used by assembly workers to manually format documents. However, the SGML concept of generalized tags is based on elements (nested ranges with annotated attributes) rather than just print effects, with also the separation of structure and tags, and HTML has been gradually moved in that direction with CSS. Berners-Lee An HTML implementation of SGML was formally defined as such by the Internet Engineering Task Force (IETF) with the mid-1993 publication of the first proposed HTML specification: the "Hypertext Markup Language (HTML)" Internet project by Berners-Lee and Dunn Connolly, whose document type SGML included a definition to define the grammar.
