(The next generation
of HTML)
Brief about html5:
In
order to bring a bullish hike in the world of internet and browsing the World Wide Web in cooperation with the Web Hypertext Application Technology Working Group
(WHATWG) is here geared up with the new generation language HTML5, the fifth
revision of HTML, It not only structures but also presents content for the
world wide web much more efficiently and effectively as compared to previous versions of HTML. It also outshines XHTML1 and DOM2HTML. It is a core technology in
the internet proposed by Opera Software. It is designed to bring consistent
understanding between the browser and the machine i.e. a language that is easily
readable to the user and understood by the machine (computer,browser,parsers
etc.).
It is also an attempt to define a single markup language that can be written in
either HTML or XHTML syntax. To encourage more interoperable implementations it
includes detailed processing models; it extends, improves and rationalizes the
markup available for documents, and introduces markup
and application programming interfaces
(APIs) for complex web applications.
New attributes have
been introduced in HTML5, while some elements and attributes have been removed.
Some elements, such as
<a>,
<cite>
and
<menu>
have been changed or revised. The APIs and document object model (DOM) are no
longer in use, but play important parts of the HTML5
specification.HTML5 also provide the feature of
error correction so that user deals with only correct syntax.
Some of the new
elements or attributes included in HTML5 are semantic replacements for common
uses of generic block (<div>)
and inline (<span>)
elements, for example
<nav>
(website navigation block),
<footer>
(usually referring to bottom of web page or to last lines of HTML code), or
<audio>
and <video> instead of
<object>.
Some elements such as
<font>
and
<center> have been removed as
these effects
are achieved using Cascading Style Sheets. It also focuses on the importance of
DOM scripting (e.g., JavaScript) in Web behavior. The HTML5 syntax is no longer
based on SGML despite the similarity of its markup. HTML5 also includes Web
Forms 2.0, a previously separate WHATWG specification.
LOOKING AT THE
FEATURES PROVIDED BY HTML5
API's
Though
it is not yet available for the official standard
but
API's like adding audio/video,
canvas element for
drawing,controls like calendar, date, time, email, url, search, drag and drop,
microdata, browser history management,offline storage database etc makes HTML5
best for
most browsers like (Safari, Chrome,
Firefox, Opera, Internet Explorer) and they continue to add new HTML5 features
to their latest versions.
