The Web Hypertext Application Technology Working Group (WHATWG) began work on the new standard in 2004. At that time, HTML 4.01 had not been updated since 2000,[8] and the World Wide Web Consortium (W3C) was focusing future developments on XHTML 2.0. In 2009, the W3C allowed the XHTML 2.0 Working Group's charter to expire and decided not to renew it.

New features in the latest (next) specification of Hypertext Markup Language (HTML), specifically, drawing on a canvas and incorporating video, provide powerful and flexible capabilities for the production of directions for folding origami models. The methodology shown here demonstrates topics in geometry, trigonometry and algebra as well as basic programming? That would appeal to teachers and students. In this paper, after providing some background on HTML5, I describe the programs for the business card frog and the talking fish.

HTML5 includes detailed processing models to encourage more interoperable implementations; it extends, improves and rationalizes the markup available for documents, and introduces markup and application programming interfaces(APIs) for complex web applications.[6] For the same reasons, HTML5 is also a candidate for cross-platform mobile applications, because it includes features designed with low-powered devices in mind.

HTML stands for Hyper Text Markup Language. It is used to design web pages using markup language. HTML is the combination of Hypertext and Markup language. Hypertext defines the link between the web pages. Markup language is used to define the text document within tag which defines the structure of web pages. HTML 5 is the fifth and current version of HTML. It has improved the markup available for documents and has introduced application programming interfaces (API) and Document Object Model (DOM).

HTML5 is the fifth revision and newest version of the HTML standard. It offers new features that provide not only rich media support but also enhance support for creating web applications that can interact with users, their local data, and servers more easily and effectively than was previously possible.

Some HTML5 features remain unsupported by some browsers. However, Gecko, and by extension, Firefox, has very good support for HTML5, and work continues toward supporting more of its features. Gecko began supporting some HTML5 features in version 1.8.1. You can find a list of all of the HTML5 features that Gecko currently supports on the main HTML5 page. For detailed information about multiple browsers' support of HTML5 features, refer to the Can I Use website.

HTML5 was first released in public-facing form on 22 January 2008, with a major update and "W3C Recommendation" status in October 2014 Its goals were to improve the language with support for the latest multimedia and other new features; to keep the language both easily readable by humans and consistently understood by computers and devices such as web browsers, parsers, etc., without XHTML's rigidity; and to remain backward-compatible with older software. HTML5 is intended to subsume not only HTML 4, but also XHTML 1 and DOM Level 2 HTML.

Due to usability purpose, the websites made by developers are highly interactive nowadays and for this developers need to include fluid animations, stream video, play music and Social Network sites like Facebook and Twitter into the websites. Till now they have only the option to integrate it with the help of Flash or Silverlight, Flex or javascript like tools. But these consume so much time to develop and even the complexity of web application also increased. But now with the help of HTML5, it is possible to embed video and audio, high-quality drawings, charts. animation and many other types of rich content without using any plugins or third party programs as the functionality is now built into the browser.

HTML 5 will enable web designers to use cleaner, neater code, we can remove most div tags and replace them with semantic HTML 5 elements.

Now it is easy to see which parts of the page are headers, nav, footers, aside, etc as the tags are specific for these all and most importantly know what their meaning and purpose is in whole the format. By using HTML5 elements we can increase the semantic value of the web page as the codes are very standardized.

HTML5 enables designer to use more fancier forms. Even it makes form validation native to HTML, User interface enhancements and reduced need for JavaScript (only needed in browsers that don’t support form types). There will be different type of text inputs, search and different fields for different purpose.

Consistency As websites adopt the new HTML5 elements we will see more greater consistency in terms of the HTML used to code a web page on one site compared to another. This will make it more easier for designers and developers to immediately understand how a web page is structured.
