What Is HTML??????
- H.T.M.L stands for hypertext markup language and is a popular language to create websites with. Think of HTML as another language, just like English or Spanish, which tells the computer how to show and render the website you created.
- Although there are a lot of other languages the computer also understands, most people use H.T.M.L, since it is more popular language, mostly because of the popularity of the English language around the world!!).
- HTML defines the structure and layout of a Web document by using a variety of tags and attributes. The correct structure for an HTML document starts with <HTML><HEAD>(enter here what document is about)<BODY> and ends with </BODY></HTML>. All the information you'd like to include in your Web page fits in between the <BODY> and </BODY> tags.
The Early History of HTML
HTML in 1990 - 1992
- Tim Berners-Lee first started to come up with code for his WWW project in 1990. The first mention of him working on code for processing HyperText can be found in the original HyperText.m file that Tim worked on, dated 25th September 90.
- From the 27th to the 30th November 1990, Tim and Robert Cailliau attended ECHT '90 - the European HyperText Convention. After ECHT '90, it appears that he had some more ideas about the (probably as yet unnamed) World Wide Web, and in the last few months of 1990, he started to produce more code, and also the first recorded HTML documents.
- In fact, the earliest HTML document on the WWW at the moment dates from 13th November - a couple of weeks before the conference - as evidenced a HTTP HEAD request, which returns "Last-Modified: Tue, 13 Nov 1990 15:17:00 GMT". The page is still functional in most modern Web browsers, and even contains a functional HyperLink!
First specifications
- The first publicly available description of HTML was a document called HTML Tags, first mentioned on the Internet by Berners-Lee in late 1991. It describes 20 elements comprising the initial, relatively simple design of HTML. Except for the hyperlink tag, these were strongly influenced by SGMLguid, an in-house SGML based documentation format at CERN. Thirteen of these elements still exist in HTML 4.
- HTML is a text and image formatting language used by web browsers to dynamically format web pages. Many of the text elements are found in the 1988 ISO technical report TR 9537 Techniques for using SGML, which in turn covers the features of early text formatting languages such as that used by the RUNOFF command developed in the early 1960s for the CTSS (Compatible Time-Sharing System) operating system: these formatting commands were derived from the commands used by typesetters to manually format documents. However, the SGML concept of generalized markup is based on elements (nested annotated ranges with attributes) rather than merely print effects, with also the separation of structure and processing; HTML has been progressively moved in this direction with CSS.
- Berners-Lee considered HTML to be an application of SGML. It was formally defined as such by the Internet Engineering Task Force (IETF) with the mid-1993 publication of the first proposal for an HTML specification: "Hypertext Markup Language (HTML)" Internet-Draft by Berners-Lee and Dan Connolly, which included an SGML Document Type Definition to define the grammar.[8] The draft expired after six months, but was notable for its acknowledgment of the NCSA Mosaic browser's custom tag for embedding in-line images, reflecting the IETF's philosophy of basing standards on successful prototypes.[9] Similarly, Dave Raggett's competing Internet-Draft, "HTML+ (Hypertext Markup Format)", from late 1993, suggested standardizing already-implemented features like tables and fill-out forms.[10]
- After the HTML and HTML+ drafts expired in early 1994, the IETF created an HTML Working Group, which in 1995 completed "HTML 2.0", the first HTML specification intended to be treated as a standard against which future implementations should be based.[9] Published as Request for Comments 1866, HTML 2.0 included ideas from the HTML and HTML+ drafts.[11] The 2.0 designation was intended to distinguish the new edition from previous drafts.[12]
- Further development under the auspices of the IETF was stalled by competing interests. Since 1996, the HTML specifications have been maintained, with input from commercial software vendors, by the World Wide Web Consortium (W3C).[13] However, in 2000, HTML also became an international standard (ISO/IEC 15445:2000). The last HTML specification published by the W3C is the HTML 4.01 Recommendation, published in late 1999. Its issues and errors were last acknowledged by errata published in 2001.
