 HTML is a computer language devised to allow website
creation  Firstly mentioned on the Internet by Berners- Lee in late 1991.  HTML stands for Hyper Text Markup Language . • An HTML file is a text file containing small markup tags . • The markup tags tell the Web browser how to display the page . • An HTML file must have an htm or html file extension  Example : Simple HTML Page Example Explained The first tag in your HTML document is <html>.

 HTML5 ~= HTML + CSS3 + JavaScript  Written
by Joshua Johnson, On 19th October 2009. Filed in HTML, Web Standards .  World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG).  Still a work in progress. However, most modern browsers have some HTML5 support. http: //HTML5Test.com

 New features should be based on HTML, CSS, DOM,
and JavaScript  Reduce the need for external plugins (like Flash)  Better error handling  More markup to replace scripting  HTML5 should be device independent  The development process should be visible to the public

 New Markup Elements  <article> Defines external content 
<aside> Defines some content aside from the article it is placed in  <audio> Defines sound, such as music or other audio streams  <canvas> Defines graphic, such as graphs or other images  <command> Defines a command button, like a radio button, a checkbox, or a button

<datagrid> Defines a list of selectable data. The datagrid is
displayed as a tree-list <datalist> Defines a list of selectable data. Use this element together with the input element, to make a dropdown list for the inputᾼs value <details> Defines details of an element, which the user can see, and click to hide  < dialog> Defines a dialog, such as a conversation .

 <nav> Defines a section ofÄ navigation links  <q>
Defines a short quotation  <time> - Defines a time or a date, or both  <video> - Defines video, such as a movie clip or other video streams  <meter> - Defines the range

 API's for multimedia by using video and audio tags
 Drag and drop API  HTML canvas 2D context  HTML5 web messaging  WebSQL  Geolocation  WebWorkers  Notification  WebSockets

 New Media Elements ◦ <video>  Now embed video
in your page without requiring any plugin like Flash or Silverlight. Browser MP4 WebM OGG IE9 Yes No No FF4+ No Yes Yes Chrome6+ Yes Yes Yes Opera10.6+ No Yes Yes

 New Media Elements ◦ <audio>  Extremely simple and
easy way to show an audio player in your page. Browser MP3 WAV OGG IE9 Yes No No FF4+ No Yes Yes Chrome6+ Yes Yes Yes Opera10.6+ No Yes Yes

 A canvas is a rectangular area, and you control

 Two new objects to save data: ◦ localStorage -
stores data with no time limit ◦ sessionStorage - stores data for one session  localStorage ◦ Data stored till cleared programmatically by JS ◦ Or browser cache cleared. ◦ accessible only from the domain that initially stored the data.  sessionStorage ◦ accessible only from the page that initially stored the data.

 email  url  number  range  date
pickers (date, month, week, time, datetime)  search  color <input type="number"> <input type="range">

HTML4 HTML5 No multimedia support without third party It has
inbuilt multimedia element in html5 like audio, video, canvas. No Threads Support of WebWorkers Drag and Drop with JavaScript API Drag and Drop without any JS API Support It was not available New tags like <header>, <footer>, <article> No Persistent Storage Persistent Storage with WebStorage API

 http://www.webworks.dk/enginetest/  Web-Based Adobe Photoshop Clone in HTML5  http://www.picozu.com/

Conclusion ᾶ  Introduced the new elements and APIs included
in HTML5.  We also got a taste of the semantic changes to come and the new structure our web pages should take in the future.  Finally, we learned that even though HTML5 isnᾼt quite ready for the masses, we can still get our grubby developer fingers on it and start experimenting today.
