The World Wide Web Consortium (W3C) released an HTML5 logo in different styles and formats, but the with the same general presentation theme. Ian Jacob's interview of Michael Nieling and the HTML5 Logo FAQ provide additional background information regarding this logo, ideas behind its creation, and motivations for its creation. There has been significant enthusiasm in the blogosphere regarding the HTML5 logo, but there have been skeptics as well. Ian Jacobs addresses some of the concerns in The HTML5 Logo Conversation.
The main HTML5 logo page provides for downloading the various logo representations (black/white, orange/white, with or without "HTML", SVG, PNG, various resolutions, etc.). A few of the logos as provided by the W3C are shown next.
The W3C not only provides the HTML5 logo itself in different formats, but it also provides icons representing various technology classes. The HTML5 Logo page has a section on which each of these eight icons can be clicked on to see a brief description of what the icon represents. The idea is that these icons can be appended to the HTML5 log either vertically or horizontally to represent which "HTML5" features a particular site supports. Here are those icons with descriptions that are even more brief than those on the HTML5 Logo page.
Semantics / Structure
Offline and Storage Class
Device Access including Geolocation
Audio / Video / Multimedia
Graphics / Effects / 3D
Performance and Integration (including XMLHttpRequest 2)
CSS3 and Web Open Font Format (WOFF)

WHATWG: HTML is the New HTML5
There was already some confusion surrounding the HTML5 logo as described in Gavin Clarke's articles W3C tackles HTML5 confusion with, um, more confusion and W3C apologizes for HTML5 brand confusion. It probably won't help matters that in the same week that an HTML5 logo was unveiled with the "5" as its central defining feature, the Web Hypertext Application Technology Working Group (WHATWG) announced that they are dropping the "5" in the blog post HTML is the New HTML5. In that post, Ian Hickson references a December 2009 message in which he stated:
I just checked in a change which moves the WHATWG from working on
versioned specifications ("HTML5") to just working on technology without
trying to version it ("HTML").
WHATWG now maintains an HTML living standard. So how is W3C's HTML5 specification related to WHATWG's living HTML standard? The best answer may be provided by the WHATWG HTML specification's "Introduction" section which addresses the question Is This HTML5? (I have added the emphasis):
In short: Yes.
In more length: "HTML5" has at various times been used to refer to a wide variety of technologies, some of which originated in this document, and some of which have only ever been tangentially related.
This specification actually now defines the next generation of HTML after HTML5. HTML5 reached Last Call at the WHATWG in October 2009, and shortly after we started working on some experimental new features that are not as stable as the rest of the specification.
The relationship between WC3 and WHATWG and their respective relationships to HTML can be a source of confusion. A good summary of these two groups and their relationship to each other and to HTML and other web technologies can be found in Dive into HTML5: How Did We Get Here? which describes the convoluted relationships between HTML5, WC3, and WHATWG. The post Reinventing HTML describes the decision in late 2006 to have the W3C and the WHATWG collaborate on "HTML5" (Web Applications 1.0).
Another interesting post for reading about what constitutes "HTML5" is the concise post HTML5 Brief: in a couple paragraphs. The post HTML5 - what is it and what’s in it for me? summarizes the observations and conclusions drawn by "just another software engineer" regarding what HTML5 is.
The "Little Things" of HTML5
The post Falling for HTML5: Finding Love in the Little Things is a summary of the "little things" in HTML5 that Felicity Evans believes "will make the world of difference to the way I code day-in, day-out." She covers HTML5 advancements such as block-level
<a>element, form placeholders, and the
Just as some enterprise Java developers gloat in their "superiority" when they know it is Java EE rather than J2EE, it seems that this is an opportunity for the same type of personalities to gloat when they know that it's now just HTML rather than HTML5. Of course, then there's the logo with the prominent "5" that's just getting started. Its main page's URL doesn't include a "5" (http://www.w3.org/html/logo/), but the logo does.
The logo with the "5", the specification without versioning, and Google Chrome's dropping of support for H.264 in its
<video>element all mean that the web development environment will remain for the foreseeable future as it has always been: inconsistent support across multiple browsers will require developers to use feature detection, graceful degradation, and other now common web development tactics as they adopt HTML5 features.
