• The HTML5 work stems from the WHATWG (Web Hypertext Application Technology Working Group), and their focus is the development of HTML and APIs for web applications.
• The reason it came to life back in 2004, founded by people from Apple, Mozilla and Opera, was a worry about the direction W3C were taking with XHTML, and no focus on HTML or the real-life needs for web developers.
• It got really interesting in July of 2009, when W3C announced that XHTML2 would be cancelled in favor of HTML. This means that the only future development of HTML and XHTML is in the form of HTML5 – HTML5 is the future, whatever you think about it.
• We should also mention right away that HTML5 is spelled just that, with no space between the the L and 5.
• HTML5 is the next generation of HTML.
• The previous version of HTML, HTML 4.01, came in 1999. The web has changed a lot since then.
• HTML5 is still a work in progress. However, the major browsers support many of the new HTML5 elements and APIs.
• HTML5 is cooperation between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG).
• WHATWG was working with web forms and applications, and W3C was working with XHTML 2.0. In 2006, they decided to cooperate and create a new version of HTML.
VERSIONS OF HTML
• HTML 1.0 was the first release of HTML to the world.
• Not many people were involved in website creation at the time, and the language was very limiting.
• HTML 2.0 was developed by the Internet Engineering Task Force HTML Working Group in 1996.
• HTML 2.0 included everything from the original 1.0 specifications but added a few new features to the mix.
• HTML 3.2 became a W3C Recommendation 14 January, 1997. HTML 3.2 contained new features such as fonts, tables, applets, superscripts, subscripts and more, to the existing HTML 2.0 standard.
• One of the elements added to the HTML 3.2 standard, was the <font> tag. This tag introduced unnecessary complexity to the important task of separating HTML content (text) from its presentation (style). The <font> tag became deprecated in HTML 4.0.
Some rules for HTML5 were established:
• Reduce the need for external plug-in (like Flash)
• Better error handling
• More markup to replace scripting
• HTML5 should be device independent
• The development process should be visible to the public
Cleaner markup / Improved Code:
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.
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 easier for designers and developers to immediately understand how a web page is structured.
Different technologies can elaborate on the features with the help of HTML5, as they can immediately make more detailed understanding of the structure of a page by take a look at HTML5 elements it has.
