HTML

H T M L(Hyper Text Markup Languge)

  1. Version history of html:

November 24, 1995:
HTML 2.0 was published as IETF RFC 1866. Supplemental RFCs added capabilities:
January 1997:
HTML 3.2[14] was published as a W3C Recommendation. It was the first version developed and standardized exclusively by the W3C, as the IETF had closed its HTML Working Group in September 1996.[15]
HTML 3.2 dropped math formulas entirely, reconciled overlap among various proprietary extensions and adopted most of Netscape's visual markup tags. Netscape's blink element and Microsoft's marquee element[13] A markup for mathematical formulas similar to that in HTML was not standardized until 14 months later in MathML. were omitted due to a mutual agreement between the two companies.
December 1997:
HTML 4.0[16] was published as a W3C Recommendation. It offers three variations:
  • Strict, in which deprecated elements are forbidden,
  • Transitional, in which deprecated elements are allowed,
  • Frameset, in which mostly only frame related elements are allowed;
Initially code-named "Cougar",[17] HTML 4.0 adopted many browser-specific element types and attributes, but at the same time sought to phase out Netscape's visual markup features by marking them as deprecated in favor of style sheets. HTML 4 is an SGML application conforming to ISO 8879 – SGML.[18]
April 1998:
HTML 4.0[19] was reissued with minor edits without incrementing the version number.
December 1999:
HTML 4.01[20] was published as a W3C Recommendation. It offers the same three variations as HTML 4.0 and its last errata were published May 12, 2001.
May 2000
ISO/IEC 15445:2000[21][22] ("ISO HTML", based on HTML 4.01 Strict) was published as an ISO/IEC international standard. In the ISO this standard falls in the domain of the ISO/IEC JTC1/SC34 (ISO/IEC Joint Technical Committee 1, Subcommittee 34 – Document description and processing languages).ajmal[21]
As of mid-2008, HTML 4.01 and ISO/IEC 15445:2000 are the most recent versions of HTML. Development of the parallel, XML-based language XHTML occupied the W3C's HTML Working Group through the early and mid-2000s.


What is HTML?

                                      HTML is a language for describing web pages.
  • HTML stands for Hyper Text Markup Language
  • HTML is not a programming language, it is a markup language
  • A markup language is a set of markup tags 
  • HTML uses markup tags to describe web pages.

    Creating an HTML Page:

                                                 A web page is created using a language called, Hypertext Markup Language, better known as HTML Code. You can write your own coding within a plain text editor, such as Note Pad, or use an HTML editor, which will write the code for you.

    HTML codes, also referred to as HTML tags, are enclosed by the lesser than (<) and greater than (>) brackets and may be written in capital or lower case letters.

    The opening bracket is followed by an element, which is a browser command, and ends with the closing bracket.

    <font size=2>

    An element may also be followed by attributes, which are words describing the properties of the element, and further instruct the browser.

    <font size=2>

    Attributes are only contained in the opening HTML tags to the right of the element and are separated by a space and followed by an equal (=) sign.

    The value follows the equal sign and is enclosed in quotes.

    <font size=2>

    Basic HTML Document Code Structure:

                                                    
                                                    Begin writing your HTML tags by creating your document's basic layout. Copy and paste this code into your text or HTML editor.
          structure of html:
     
  • <html>
    <head>
    <title>Your Page Title</title>
    </head>
    </body>

    This area will contain everything that will be visible through a web browser, such as text and graphics. All of the information will be HTML coded.

       For example:

     HTML codes, tags and examples, see the HTML chart below:

                  
    <html> - Begins your HTML document.

    <head> - Contains information about the page such as the TITLE, META tags for proper Search Engine indexing, STYLE tags, which determine the page layout, and JavaScript coding for special effects.

    <title> - The TITLE of your page. This will be visible in the title bar of the viewers’ browser.

    </title> - Closes the HTML <title> tag.

    </head> - Closes the HTML <head> tag.

    <body> - This is where you will begin writing your document and placing your HTML codes.

    </body> - Closes the HTML <body> tag.

    </html> - Closes the <html> tag.
