Synopsis
<source>
(XHTML:
<source/>
or
<source />
)
Not in HTML 4.01
. Used within
audio
and
video
elements,
source
allows authors to speci-
fy multiple versions of a media file. When
source
is used, the
src
attribute should be omitted
from the
audio
and
video
elements. A user agent will go down the list of
source
elements
until it finds a format it is able to play.

This is an empty (void) element, meaning it has only a start tag and may not have any con-
tents. In HTML, the end tag is forbidden. In XHTML, the element must be closed with a
trailing slash (
<source/>
or
<source />
).
