Article introduction of Wulin.com (www.vevb.com): HTML5 is said to have received support from most platforms.
According to foreign media reports, Mark Pilgrim, an executive of Google's developer business unit, said at the WWW2010 meeting that although further improvements are needed, HTML5 has received support from most platforms and is suitable for completing most tasks.
But not everyone thinks that HTML5 has matured. Jeffrey Hammond, an analyst at Forrester, published a report last week that in the long run, HTML5 may replace some rich Internet applications (RIM) platforms, but not yet. HTML5 will have a significant impact on the development of web applications, but it is only a complementary rather than an alternative technology leading the RIA platform.
Pilgrame said that the beta version of IE 9, Safari, Chrome, Firefox and Opera all support HTML5 to varying degrees, and Apple iPhone and Google Android also support many features of HTML5. Although not all HTML5 features are supported by the browser, many major features are supported, including semantic tags, forms, multimedia, geolocation and offline web applications.
Pilgram admits that browser manufacturers still have differences on the video technology supported by HTML5. Safari only supports H.264 format, Firefox and Opera only support Ogg Theora, and Chrome supports both video formats. Microsoft published a blog post on Friday local time saying that IE 9 will only support H.264, which means IE 9 does not support Ogg Theora.
Google uses geolocation features in search apps for iPhone and Android, and Twitter also uses that feature. In addition, Google uses offline web application functions in the iPhone version of Gmail application.
Pilgrame says web developers should start learning new features of HTML5
