A brief history of the interweb


  • It all began with “Hypertext” : (over/beyond – text)


  • Tim Berners-Lee & Co
    • HTTP – HyperText Transfer Protocol
    • HTML – HyperText Markup Language
    • Need for standardisaton – Hypertext languages were system specific.
    • First browsers emerge – Mosaic + Lynx

A brief history of the interweb


  • 1994
    •  World Wide Web Consortium (W3C).
    • HTML 2.0.


  • 1996
    • HTML Editorial review board is formed : Involving IBM, Microsoft, Netscape, Novell, Softquad and the W3C.


  • 1997
    • HTML 3.2 is recommended by W3C.

A brief history of the interweb



  • 1998
    •  HTML 4.0 is released as a W3C recommendation.


  • 2000
    • XHTML 1.0 : Combined HTML 4.01 + eXtensible Markup Language (XML) 1.0 .
    • Able to include pieces from other XML based languages, e.g. Scalable Vector Graphics and MathML.

A brief history of the interweb

  • 2002
    • W3C commented - "The XHTML family is the next step in the evolution of the Internet. By migrating to XHTML today, content developers can enter the XML world with all of its attendant benefits, while still remaining confident in their content's backward compatibility"
  • 2004
    • Web Hypertext Application Technology Working Group (WHATWG) formed (Apple,Firefox,Opera) in response to the slow evolution of W3C's web standards.
    • Another motivation was the W3C's new direction toward XML based technologies.

A brief history of the interweb



  • 2007
    • W3C discontinues XHTML development and pursues working on the HTML 5.0 standard with WHATWG.



  • 2014
    • HTML 5.0 recommendation expected from W3C

Framework : Basic 3 Components 



HTML – HyperText Markup Language

CSS – Cascading Style Sheets

Javascript




Framework : Static vs Dynamic


Static

  • Generally just HTML, CSS and some basic Javascript.
    • As a noticeboard to give static information.

    Dynamic

    • Everything from static except additional interactive user input through  Javascript.
    • Server based.

    • Used for shopping, forums and games.

    Framework : Server-Client Model

    <html>   
        <header>
       
        </header>
        <body>
            <h1>My First Heading</h1>

    HTML - template


    General remarks


    The HTML document starts with <html> and ends with </html>.
     
    HTML is case insensitive.
     
    Everything in HTML is implemented in the form of tags and elements.

    HTML - Template


    Tags and elements.


    Element = <tags> content </tags>


    Tags and elements can be and are frequently nested inside each other.


    Usually tags come in pairs but there are a few exceptions.

    Head

    The <head></head> element contains info for the browser.


    <title> - document title

    <style> - styling instructions (e.g. - internal css)
