Dive Into HTML5 elaborates on a hand-picked selection of features from the HTML5 specification and other fine standards. We encourage you to buy the printed work — Mark Pilgrim’s artfully titled “HTML5: Up & Running” — published on paper by O’Reilly, under the Google Press imprint.

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.

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, many features are already supported and 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.
