Abstract:

The 'video' element is brand new in HTML 5 and allows you to, get this, play a movie in your website! The data of this element is supposed to be video but it might also have audio or images associated with it. Of course, this will only work in a few browsers: Safari 3.1+, Firefox 3.5+, and latest builds of Opera (oh, and potentially the next release of Chrome).
