HTML Tag: source

Alternative media resource for video and audio elements. A browser should embed the first resource it can — if it gets befuddled with one, it can move on to the next in a list.

source elements should only be used if their video or audio parent does not have a src attribute.

source has no content and therefore does not warrant a closing tag.

Required Attributes

src The location of the alternative media file to be used. URL.
