The reasons for these incompatibilities are complex and are related to licensing issues for the
video and audio codecs (the compression techniques used to reduce fi le size). To use these
new tags, you should provide multiple versions of your video and audio, thereby allowing
the browser to choose the fi rst supported format it can fi nd; so a more reliable method of
providing video might look like this:
Note that older browsers that do not support the video and audio tags will need an alternative
way of playing video; currently, the best way to provide this capability is to add the option to
use Flash video, which is widely supported in current and older browsers.
The documentation for HTML5 is updated constantly; however, one of the best online resources is
Mark Pilgrim’s “Dive into HTML5” resource, located at http://diveintohtml5.org/video.html.
Provide drawing and animation features using the
element
The
element works as a drawing surface on your page. Within this drawing
surface, you can create shapes, colors, gradients, and pattern fi lls.
This example might be visually unremarkable, but the
addition of a native drawing format in HTML is notable.
