You must include the
video source in both the
MP4 and WebM formats
to ensure support across
all of the major browsers.
<source src=”rwdance.mp4” />
<source src=”rwdance.webm” />

The video element supports many of the same attributes as the audio element. For
example, to display video controls, you add the attribute controls=”controls” to the
<video> tag. Figure 7-22 describes the other video attributes supported in HTML5.
