W3C introduced a new logo program for HTML5. A logo with a consistent visual design is an important indication of the growing maturity of many components of HTML5. As developer and site owners see this logo across the web, we hope it'll signal that while there's still a lot of work to do until all the HTML5 technologies are ready, real sites are starting to take advantage of them today.
The proposed HTML5 logo "is a general-purpose visual identity for a broad set of open web technologies, including HTML5, CSS, SVG, WOFF, and others," according to the FAQ page. However, the logo "doesn't imply validity or conformance," the W3C noted.
W3C is encouraging vendors, Web-site/app developers and others to use the logo on their sites, t-shirts and stickers to raise the visibility of HTML5. If the community embraces the logo, W3C "will adopt it as its own official logo for HTML5 in the first quarter of 2011," the FAQ said.
Microsoft's planning to promote the logo immediately on "the major Microsoft HTML5 properties," including the IE 9 test drive site and its associated Beauty of the Web site. The W3C site lists html5rocks.com, Modernizr and "a host of other sites and apps" as being early advocates for the new logo and/or its component parts.
