According to Wikipedia, “HTML5 (HyperText Markup Language, version 5) is the fifth major revision of the basic language of the World Wide Web, HTML.” Its development began in 2004 and is scheduled for completion until 2014.
HTML5 means the evolution of Web technologies and to problems such as Flash Player. Because not only web HTML5 are also compatible with browsers complications and smartphones, which are already changing everything.
With the following graphics we propose a journey through the history of HTML5, from creation to the time acts l, stopping at some of the most outstanding events of this trip is yet to conclude.
The history of HTML5
Tim Berners-Lee created the HTMLoriginal 1989 to address shortcomings in existing methods of access to information on the Internet. Since its inception, find a path around the internet was a difficult task.The content was as Internet documentsindividual, with no easy access method to navigate between them. You basically had to know the addresses of the documentswere being sought and enter them by hand.To solve this problem, Berners-Lee created two technologies: HTTP (Hypertext Transfer Protocol) and HTML. (Recommended: What I do not know the first server in the story)
HTTP is a transfer protocol used by web servers to serve content . The start of a URL in your browser (assuming that the browser displays the URL) will begin with http:// . This part of the URL tells the browser the type of protocol to use when making the request to the server. When the server receives the request for a document , this document is already written (or will become) to HTML. The document below is what is sent to thebrowser , in response to your request.
HTML is a markup language that tells the browser how it should present the content .Links to other documents can be present in your content , providing an easy ( user-friendly ) to navigate between documents on the Internet.
The combination of HTTP and HTML provide a fast and easy to navigate between different documents , just by clicking on text links. After the creation of these two technologies, Berners-Lee founded the World Wide Web Consortium (W3C) . The W3C was the driving force in the first four versions of HTML.
The Internet was originally intended to servedocuments simple text. The first explorers were text-based (no windows or anything, it was only text on the screen). Even the addition of images was a big deal when first introduced. Now, people do everything from sending emails to watch TV online. The Internet has become much more than a mechanism for transporting documents to plain text. With new features and uses come new challenges and problems that HTML was not designed to handle.
The W3C tried to address the problems of the current Internet standard HyperText Markup Language Extensible (XHTML) 2.0. However, this standard was not well received and, for the most part, has been abandoned. In 2004, while focused on the W3C XHTML 2.0 standard, a group called Web Hypertext Application Technology Working Group ( WHATWG ) began work on the HTML 5 standard, which was better received than the XHTML 2.0 standard. In 2007, the W3C XHTML 2.0 standard left and is now working with the WHATWG on the development of HTML5 (but also with its variant XHTML5).
It must be said, as pointed out by the HTML5 specification, that the specification published by the WHATWG is not identical to the specification published by the W3C. The main differences between the two versions are that the WHATWG version includes features not included in the version of the W3C: Some of them are omitted, but may be considered for future revisions of HTML, HTML5 beyond, and other features were omitted because in the W3C specifications have been published as separate.
Right now, HTML5 has not been officially released . Most of the contents of the website are still being written to the HTML 4 specification. However, several browsers include support for HTML 5 specification.
Because each browser can support only some of the features of HTML5, things can be a bit heavy. Before writing a website based on HTML5, must prove each of the browsers (or at least the most used) to make sure it has the features or functionality that we use on our site.
