Continuing my little series of upcoming web standards soon to be included in most browsers (only the Steve’s at MS know if IE will include CSS3 & HTML 5), here are some examples of HTML 5 out in the wild. Apple’s Safari browser, and the beta of Firefox support these HTML 5 features.
Youtube HTML5 Demo
Not only does this Youtube demo use <header> & <footer>, <nav>, and <article> tags but it uses the promising <video> tag which eliminates the need for <embed> and <object> tags which require browser plugins to display video in a browser. Google also demonstrates some 3D graphic rendering in the browser, using O3D, an open-source web API for creating rich, interactive 3D applications.
