Let the point on HTML5

In an article a couple of years ago we already talked about the news that HTML5 is preparing to introduce in Web publishing, with this article we'll investigate further the argument is a point of view of "historical" than technical in order to make point on the current status of the work.

Historical reasons behind the evolution of HTML

HTML4, released back in 1999 and designed by the W3C Consortium, had enhanced the capabilities of the now old HTML 3.2 using an extension and innovation is not just radical but still very consistent, as a result of new requirements from the expansion of the world richest promising Internet and the spread of personal computers.
The world of PCs during the 90s, in fact, was mainly characterized by an activity (if not totally) offline for the vast majority of users, while in the advent dell'HTML4 was beginning to feel that, from there to Little would have been a turning point in the ground connection to the Internet. With the growth of the Internet, so even its language - HTML, in fact - had to be adapted to new circumstances and needs.

Today, with the increase in computer performance and speed of connection to the Internet (thanks to ADSL and mobile technologies, wearing contact such as Wi-Fi and 3G), presented the need for a new update of the HTML language that, in these recent years, has undergone a veritable "invasion" by technologies (such as Flash and Javascript) which aim to overcome the limitations of the old markup language, introducing new forms of Web content more dynamic and multimedia ( Web 2.0, in fact, is characterized by an increasing spread of technologies that tend to exceed the HTML now confined to the role of "mere structural scaffold").

In this grows and develops the 'HTML5 whose aim is precisely to meet the new needs of users of the Internet also trying to anticipate possible future developments.

Major innovations of HTML5

What's new in HTML 5 aims to improve the modularity of the characteristic elements of a web page, so as to have a code more structured and orderly.
Secondly HTML 5 supports local storage of data downloaded via the same browser. In this way, applications that require offline storage (which are currently implemented with external plugins) can be managed directly by the standard and without recourse to ad hoc software (perhaps best known example is Google about this case that requires the presence of Offline Google Gears).
Below is a list of technical innovations and the most consistent features of the new version of the language:

• becomes the standard and short doctype: <! DOCTYPE html>
• as far as possible, we try to limit the use of scripts, delegating the HTML to do all the work;
• the structure of the text is more rigorous and complete, there are explicit subdivisions into chapters and paragraphs;
• There are specific tags for each section of the page (table of contents, headers, footers ..) that is deployed manually with the first div tag is now separated semantically using specific commands; Below is an explanation about the relationship between subdivision and new tags:
