HTML5 - Wikipedia, the free encyclopedia
HTML5 is a language for structuring and presenting content for the World Wide Web , and is a core technology of the Internet originally proposed by Opera Software . [ 1 ] It is the fifth revision of the HTML standard (created in 1990 and standardized as HTML4 as of 1997) [ 2 ] and as of April 2012 [update] is still under development. Its core aims have been to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices ( web browsers , parsers , etc.). HTML5 is intended to subsume not only HTML 4 , but XHTML 1 and DOM Level 2 HTML as well. [ 2 ]

HTML 5 Reference
It is useful to make a distinction between the vocabulary of an HTML document—the elements and attributes, and their meanings—and the syntax in which it is written. HTML has a defined set of elements and attributes which can be used in a document; each designed for a specific purpose with their own meaning. Consider this set of elements to be analogous to the list of words in a dictionary. This includes elements for headings, paragraphs, lists, tables, links, form controls and many other features. This is the vocabulary of HTML. Similarly, just as natural languages have grammatical rules for how different words can be used, HTML has rules for where and how each element and attribute can be used.Note: Only supported in IE6 and IE7 on elements with a display of "inline" by default. Alternative properties are available to provide complete cross-browser support. Note: IE7 does not support "inherit" as a value on any of these properties. IE8 has some bugs with max-width/height combined with overflow: auto/scroll. Method of setting the transparency level of an element

The HTML5 test - How well does your browser support HTML5?
The HTML5 test score is an indication of how well your browser supports the upcoming HTML5 standard and related specifications. Even though the specification isn't finalized yet, all major browser manufacturers are making sure their browser is ready for the future. Find out which parts of HTML5 are already supported by your browser today and compare the results with other browsers. The HTML5 test does not try to test all of the new features offered by HTML5, nor does it try to test the functionality of each feature it does detect. Despite these shortcomings we hope that by quantifying the level of support users and web developers will get an idea of how hard the browser manufacturers work on improving their browsers and the web as a development platform.HTML 5 experimentation and demos I've hacked together.
