<source/> Tag Syntax
Rules for coding HTML source/
elements
<source .../>
<source/> Content Model
Contents of the source element
Content: Empty. All properties are coded using attributes.
Since the <source/>
tag is a void element, it is not allowed to have any content, even HTML comments and therefore should always be coded as a self-closing standalone tag, ending with the delimiter string />
rather than just >
(<source .../>
).
