New Features


THere are many new element and tags are introduced in html5 which totally change the concept of html.Before html 5,it thought that this is use only for structure.This is not able to design or can not take part in Development process directly.But now with canvas, Scalable Vegtor Graphic(SVG) and web storage it is possible to design and develop the website without help of any other helping  Language
So Lets Started To Explore what is New and Its usability

Video/audio


Now We can directly use video and audio element in our website without help of extarnal Plugin like flash or
sockwaver.This is very much easy and make website faster and reduce the browser presser to show the audio and  video element.How ever it gives full control about how audio or video are played in web pages.Moreover,this two tag is easy to use.

Canvas/SVG


 where  canvas is use !
Like the professional artist who draw arts or photograph in canvas by using color and many tools we may able to draw our own image by using html5 canvas tags tools in association with javascript.

Sill now we use images or vector grahics to make the looks of our site nice.Such as to show a graph or animation or simple drawing.This images make web pages heavier and user have to wait a long time to load this page.Which is not expected.
Now by using canvas we may able to do draw our own graphics and create our own animation and so on.Just by code.

Web Storage

web storage is one of the magic of  HTML5 specification.In previous web developer only store information on user agent (client's browser) by using cookies.There are many limitation of using cookies.But in html 5 web storage specification this problem solved completely.Web developer may now able to store 5 mb to 10 mb data on the user's browser.Unlike cookies this storage do not communicate with server.As a result it saves a lot of Bandwidth.
A real world example is in shopping cart.Now when visitor add a product on shopping cart it will tempory store in browser and when all of the products list will complete and user submit buy button then this list will goes to the server for further process.Without web storage,every time when visitor add a product to the shopping cart then it will added to the database and then shows to the list.This will make busy the server.
