So the new tags don`t add any new attributes in comparison to a normal span/div? regards, Martin On Fri, Dec 11, 2009 at 11:41 PM, Jim Driscoll <Jim.Driscoll(a)sun.com <mailto:Jim.Driscoll@sun.com>> wrote: HTML5 has a number of new semantically meaningful tags. See here for a painless introduction: http://www.techradar.com/news/internet/why-html5-is-here-today-and-not-20... Block tags include: article aside footer header nav section Inline tags include: details figure mark time Then, there's the canvas, audio and video tags. We can actually support many of these tags with only a minor change in to the panelGroup tag. In addition to the currently allowed "inline" and "block", I would add the following: span div article aside footer header nav section figure mark details and time deserve their own tags, I think, as do canvas, video and audio, and are not part of this proposal. We may wish to consider deprecating inline and block. We've never deprecated attribute values before, but hey, first time for everything. Note that for backward compatibility with particularly lame (IE) browsers, a shiv needs to be included in the page, as found here: http://code.google.com/p/html5shiv/ Whether this would be included automatically, should, I think, be implementation specific. Please comment on this proposal, and I'll add it to the spec issue tracker after we have consensus. Jim P.S.
