HTML5 is the next big thing in the web design world. The main difference with HTML5 compared to its predecessor, HTML4, is the presence of semantic markup. In previous versions of HTML, specific tags such as

(for a block element), (for an inline element), (for an element in the footer section of a page), etc. were used. In HTML5, you’ll be able to use markup such as Example Item to define arbitrary elements and their relationships.

RDF, OWL, and XML

The Resource Description Framework (RDF), Web Ontology Language (OWL), and Extensible Markup Language (XML) are used to semantically describe elements, ie. arbitrary things such as people, events, car parts, etc. HTML on the other hand, was limited to describing documents and their relationships (links) to other documents. While XHTML attempted to make more use of semantic markup, HTML5 plans on taking full advantage of these object-oriented attributes.

How Long Before We See HTML5?

It has been ages since the HTML (HyperText Markup Language) specification and technology has been upgraded, and it appears it will be ages before HTML5 is fully implemented and used in the broader web market. In fact, the editor of HTML5, Ian Hickson from Google, did not see HTML5 reach the “W3C Candidate Recommendation Stage” until December 2012 (the original planned date was the end of 2010, and W3C Recommendation (official implementation) until 2022!

HTML5 to Replace Proprietary Technologies (ie. Flash)

Nevertheless, as with past HTML releases, many parts of the HTML5 specification, particularly those that will replace proprietary plug-in technologies such as Adobe Flash, Microsoft Silverlight, and Sun JavaFX, are stable and are in the process of being implemented in products. The

HTML5 Validator

Like the industry standard for all web design coding, with the new HTML5 comes the need for an HTML5 Validator. While there are plenty of third-party validators out there, you’re best off using the official W3C (World Wide Web Consortium) engine at validator.w3.org. Most third-party validators either use this engine or are based off it. But since the W3C ultimately determines the standards and specifications of HTML5, you’re best off going to the source.

html5 validator

As you’ll see, you can validate by URI (web address), File Upload (upload your HTML5 file), or Direct Input (copy and paste your HTML5 code). You’ll see that an HTML5 (experimental) validation option is available already. By using this HTML5 validator on a regular basis as you begin to adopt elements of the HTML5 standard in your projects, you’ll be kept abreast of the technology as it evolves and matures, and will be ready to implement it in full once it reaches its final release/ acceptance stage.

Good article, although let’s get real here – just as with HTML/ HTML Transitional/ XHTML and the various associated minor revisions to these specifications – it will probably take eons for HTML 5 to become a reality. Not the specification, mind you – but the adoption of the new method by the Internet and web designers at large.

Just look at how many websites continue to use deprecated HTML 4.0 elements (such as <font> tags instead of inline style elements, <b> instead of <strong>, <i> instead of <em>, etc.)…

I really hope browser support improves for the new tags in html5, especially Internet Explorer. Because all those leftovers from the browser wars mix with the large amount of usage on IE and that forms one of the biggest things that are limiting the number of sites using html5.

My first question to the author of this article, or to anyone who has the information about HTML5, is: Why will it take so long to reach the official implementation stage? With the expected recommendation in 2022, you would think that by that time HTML5 will be more than obsolete, and most of the machines that are coming out will not be able to read it anyway by then. Ten years in the technology world seems quite excessive for an official implementation, although perhaps I am mistaken and this is actually quite standard for such technology. One reason that the… Read more »

Seeing HTML finally make some updates to the coding language is a positive thing as far as how the internet will change because of this. Among other programming languages, those for CSS and JSON were beginning to make up a lot more of the internet code than in the past. CSS in particular was gaining popularity with many web content servers and host software programs. When I first began coding web pages and blogs back in 1995, HTML was the best and only real choice for coding web content. Now, as technology continues to advance, it has become much more… Read more »
