HTML5 is a new version of HTML 4.01. It is nothing new, its feature like the API’s, Semantics et al are widely known. However, the standard HTML, has now been updated with few additional features are absolutely awesome. During its evolution, many elements, attributes and API’s have been added. The awesome features include elements or attributes that will trigger warnings in conformance checkers.
1. New Doctype and Charset:
HTML 5 is no longer part of SGML and is a markup language in itself. The HTML 5 doctype, is very simple and streamlined:
<!doctype html>
For the character set, HTML 5 utilizes the UTF-8 which can be defined with a single meta tag:
<meta charset="UTF-8">
2. New Inline elements:
Most of the new inline elements in HTML 5 are for time and are semantically marked up.
<time> - indicate that the content refers to time or date
<meter> - indicate content that is a fraction of a known range
mark> - indicate content that is marked in some fashion
<progress> - indicate the progress of a task.
3. New Dynamics Pages Support:
The motive of introducing HTML 5 is to make the tasks of creating dynamic web pages easy for the web developers of a software development company.
Ø href is not required on a tag. – Like earlier, there will be no need of an anchor while using the tag with scripts and in web applications.
Ø <details> - It provides details about an element. Thus, it acts like a tooltip.
Ø <command> -Whenever a dynamic element is activated, it defines actions that should happen
Ø <datagrid> - creates a table after gathering the information from a database or other dynamic source
Ø <menu> - Allows menu system creation on the Web pages
Ø async attribute - This is added to the script tag to tell the browser that the script should be loaded asynchronously to avoid slow loading and display of the rest of the page.
Ø Context menus - Supports the creation and use of context menus within Web pages and applications.
4. Exciting Elements:
There a few more elements offered by HTML 5 that make it more and more lovable. It allows to add audio and video by writing simple tags. Also, it allows to add graphs and images to tool tips and also makes it easy to create dynamic graphs on the web pages.
<video> to add video
<audio> to add audio
<canvas> for graphs and images.
5. New Structure:
HTML 5 recognized that the web pages too have a structure that includes header, footer, body and so on and have created tags to define the structure of a web page.
<body>
<header>
<nav>
<article>
<figure>
<section>
