HTML5 Benefits for Users and Developers

You may not realise it but you are probably already using a browser that is compatible with HTML 5. It is estimated that about half of all Internet users are already using browsers which are ready for HTML 5. Firefox (version 3.5 and higher), Chrome, Safari and Opera are the most popular of these HTML 5-compatible browsers, though the support is partial at this stage. Microsoft's Internet Explorer 8 also has support for many of HTML5 features.

HTML 5 was developed give developers more flexibility, do more things in-house and enable more exiting and interactive websites and more powerful and efficient applications. It brings HTML up to date in terms of what developers have been struggling to do with HTML4 via plugins etc., including managing data, drawing, video and audio, and to provide websites that deliver what the users want better and faster. It will eventually make it easier for developers to develop cross-browser applications for the Web and portable devices.

 

HTML 5 introduces lots of new tags and enhancements for a wide range of features including form controls, APIs, multimedia, structure, database support and faster processing. Note that the specification is still being worked on and it could be some time before it is completed, completely and universally adopted and recognised as a common standard by all browsers. User will of course have to update their browsers to benefit form the enhanced features.
 

Benefits of HTML5?

A major benefit is better Direct HTML Support for Drawing, Animation, Video and Audio

Drawing, Video and Sound - Web Developers have been increasingly trying to create applications which display fluid animations, stream video, play music and integrate with Social Network sites such as Twitter and Facebook. In most cases they could only provide these things by learning and applying add-on tools included Flex, Flash or Silverlight or building complex javascript tools. This increased the complexity and the time it took to develop the Web Applications. HTML 5 changes this with DOM and HTML support, (without the plugins and 3rd party programs) for video and audio embedding, high-quality drawings, charts and animation and many other types of rich content demanded by users.

• The new canvas element provides developers with a very powerful and very simple way to using pure Javascript to draw diagrams, graphics and dynamic animations on a web page. A good example is Mozilla’s BeSpin tool that is written in Javascript and HTML 5. Developers can use stand-alone HTML to create sites with interactive pictures, animation, charts and graphs, game components, and whatever else they by directly developing the program code and user interaction.

• The new HTML 5 video element makes it just as easy to embed video elements on a web page as it has been to embed images using HTML4 and the older HTML standards. Again no plugins, or 3rd party software attachments are required. It includes timed playback and other great new features.

Geolocation

The new HTML 5 geolocation APIs make location, whether generated via GPS or other methods, directly available to any HTML 5-compatible browser-based application. A good example is the Google Latitude for the iPhone. This is a pure Web App not a platform-dependent iPhone application.

Client-side database

HTML 5 provides a new SQL-based database API that can be used for storing data locally, that is client side. You get fully defined and structured database storage. This allows a developer to save structured data client-side using a real SQL database. It is not a permanent database, but enables you to store structured data, temporarily. The data can be accessed to support the web application and it can even be accessed when the client is disconnected for a short period of time. This database can be used to store e-mails or shopping cart items for an online shopping site.

Offline Application Cache

An offline application HTTP cache that can be used to make sure applications are available even when the user is disconnected from their network. All browsers have a cache but they have been very unreliable for delivering whole pages and applications. Mostly the browser would not cache the page properly and so you would be unable to view the page when you disconnected from the Internet. HTML 5 provides a smart solution by allowing a developer can specify the files that the browser should cache while online. So, even if you reload the page from the cache when you are offline, the complete page will still load correctly.

Thread-like Operation

Web workers is a tool for spawning background threads to speed up the browse application processing. The API allows developers to make background workers that run scripts simultaneously to the main page script. This allows for faster thread-like processing with coordination via message-passing mechanisms.

Smarter forms

HTML 5 offers enhanced forms with improvements to text inputs, search boxes and other fields and provides better controls for validating data, focusing, interaction with other page elements on the page and various other improvements.

Sharper focus on Web application Requirements

HTML 5 is aimed at making it easier to build search front-ends, wikis, real-time chat, drag-and-drop tools, discussion boards and many other modern web elements into any site, and have them work more efficiently.
