HTML5: source – media source

source – media source # T

The source element enables multiple media sources to be specified for audio video .

Content model #

source = empty & source.attrs

Attribute model #

source.attrs = common.attrs & src & type ? & media ?

Element-specific attributes #

src = uri: The address of the media source.
type = mimetype: The type of the media source (used for helping the UA determine, before fetching this media source, if it can play it).
media = mediaquery: The intended media type of the media source (used for helping the UA determine, before fetching this media source, if it is useful to the user).

Tag omission #

The source element is a void element. A source element must have a start tag but must not have an end tag.

Permitted contexts #

video.elem.flow = (video.attrs.src | source *), (normal-character-data & common.elem.flow *)
video.elem.phrasing = (video.attrs.src | source *), (normal-character-data & common.elem.phrasing *)
audio.elem.flow = (audio.attrs.src | source *), (normal-character-data & common.elem.flow *)
audio.elem.phrasing = (audio.attrs.src | source *), (normal-character-data & common.elem.phrasing *)

Details #

Each separate media source specified within a source element is a complete set of media data — for example, a complete video file, or a complete audio file).
