HTML5 development is a developing field nowadays as a result of the tremendous assortment of mixture and local applications that might be made utilizing it. Truth be told, it is popular in a substantial go of divisions from financial services to retail to social insurance. Developers can think of single applications that offer a ton of helpful characteristics, being greatly unpredictable in nature. A confirmation to its prevalence is that it has surpassed Flash in fame.

4. Preface
Just three months are like a year if you spend it on web. This is the
pretty experience of much of the web developers. Sometime before
HTML5 and CSS3 looks like far off in the way but now many
companies are using this technologies.
HTML5 and CSS3 is a building block for the next era of web
applications. Here we are going to find about all the ways you can
use HTML5 and CSS3.Before starting let’s t have a look on HTML5
and CSS3 buzzwords.

5. HTML5: The Platform vs. the Specification
HTML is a specification that describes some new tags &
markup, as well as some wonderful JavaScript APIs, but it’s
getting caught up in whirlwind of hype and promises. In some
cases pieces from the CSS3 specification such as
shadow, gradients and transformations are being called
“HTML.”
We’ll focus on the HTML5 and CSS3 specifications themselves
and how you can the techniques they describe. We’ll look into
a suit of specifications that were once part of HTML5 but are in
use right now on multiple platforms.

7. How This Works
Here we focuses on a specific group of problems that we can solve
with HTML5 and CSS3. We introduce you to specific concept and
walk you through building a simple example using the concept.
We are focusing on what you are using today. There are more
HTML5 and CSS3 features that aren’t in widespread use yet. So let’s
start your web journey with us.

8. An Overview Of HTML5 & CSS3
HTML5 and CSS3 are two new
standards proposed by W3C and
its working groups. It is a new
era of technologies you use
every day for web applications.
Before we dive in deep details of
HTML5 and CSS3 let’s talk
about some benefits and
challenges we’ll face.

9. A Platform For Web Development
A lot of new features of HTML center around for creating web
based applications. From more descriptive tags and better cross site
and cross window communication to animations and multimedia
support, developers using many HTML5 and CSS3 have a lot of new
tools for better user experience and to make richer and more
interactive applications on the web.
Now the question is that how HTML5 and CSS3 provide advance
benefits in web application? You will see how all of those
unpredictable benefits you will gain. So let’s start.

10. Backward Compatibility
If you have worked with HTML or XML you’ve come across the
doctype declaration before. It is used to tell validators and editors
what tags and attributes you can use and how the document
should be formed. Lot of web browsers used it to determine how
the browser will render the page. A valid doctype causes browsers
to render pages in “standard mode.”

12. 1.Improving User Interfaces
1.1 New Structural and Tag Attributes
I’d like to talk about a serious problem affecting many web
developers today. Most of the developers affected by Divitis ,they
wrap elements with extra div tags with IDs such as
banner, sidebar, article, and footer-is rampant.
HTML5 specification provides a cure in the form of new semantic
tags that describe the content they contain.
For example:
<header> Defines a header region of the page or section.
<footer> Defines a footer region of the page or section.
<nav> Defines a navigation section of the page or section.

13. 1.2 Creating User-Friendly Web Forms
You turn to Prototype or JQuery, or you roll your own controls and
features using a combinations of HTML,CSS and JavaScript. Now here are
the some new attribute to turn any HTML field into a user input control.
For example:
Email field [<input type=“email”>]
Display a form field for email address.
URL field [<input type=“url”>]
Display a form field for URLs.
Search field [<input type=“search”>
Display a form field for search keywords.

14. 2.Making Better User Interface With CSS3
2.1 Building Mobile Interface with Media Queries
We’ve been able to media specific style sheets .We can use media
queries to determine the following:
• Resolution
• Orientation
• Device width and height
• Width and height of the browser window

15. 3. Improving Accessibility
3.1 Providing Navigation Hints with ARIA Roles
HTML5’s new role attribute lets us assign “accessibility” to each
element on your page..Accessibility for Rich Internet Applications
(ARIA) is a specification that provides ways to improve the
accessibility of websites. There are classification of roles that you
can put to use now are landmark role and document role.HTML5
says that some elements have default roles and can’t be overridden.

16. 4. New Sight & Sound
4.1 Drawing On Canvas
Canvas is nothing but a 2D drawing platform within the browser
that uses nothing more than JavaScript and HTML with no plugins.
Canvas is extensible through a JavaScript API. Now it is openly
developed as a W3C specifications. There are the some feature and
uses of canvas:
• Canvas is bitmap system
• Used for data visualization
• Animated Graphics
• Web applications
• Games

17. 4.2 Eye Candy
ONE of the first things you'll notice about the new Windows Vista
operating system from Microsoft is the serious amount of eye candy
that comes at you.
It requires the new graphical user interface that makes better use of
today's powerful graphics hardware. You need a minimum of 128MB
of video memory on your 3D graphics card, 1 gigabyte of system
memory and a processor running at 1 gigahertz to enjoy the show.

18. 5.Future Enhancement
5.1 CSS Transitions
Interaction invitation are important to good user experience
design, and CSS has supported pseudoclasses so that we can do
some basic interaction cues on our elements.

19. 5.2 WebGL
WebGL describes how to work with 3D objects. The WebGL
specification isn’t part of HTML5, but Apple, Google, Opera, and
Mozilla are part of the working group and support in their browsers.

20. 5.3 Indexed Database APIs
Index Database API is a key/value store similar to the web storage
APIs like localStorage and sessionStorage, but it provides methods
for performing advanced queries.

21. Conclusion
If you follow the progress of HTML5 and CSS3 and stay up-to-date
with what’s happening, you’ll be fine. All these are not final
specifications for web development anything in those could
change. While Firefox, Chrome, and Safari have strong HTML5
support. But before you think too much about the future, let's start
working with HTML5.
