HTMLMediaElement

An abstract interface — no tag creates one directly. Extends HTMLElement → Element.

Reflected properties

All setters are guarded and throw NoModificationAllowedError on a read-only document.

Property	Attribute	Type	Notes
`src`	`src`	string	Reflects verbatim — no base-URL resolution.
`crossOrigin`	`crossorigin`	nullable enum	Keywords: `anonymous` · `use-credentials`. Missing attribute → `null`; any other present value → `"anonymous"`; assigning `null` removes the attribute.
`preload`	`preload`	string	Reflects the content attribute verbatim.
`autoplay`	`autoplay`	boolean (presence)	Reading reflects whether the attribute is present; writing `false` removes it, any other value sets it present.
`loop`	`loop`	boolean (presence)	Reading reflects whether the attribute is present; writing `false` removes it, any other value sets it present.
`controls`	`controls`	boolean (presence)	Reading reflects whether the attribute is present; writing `false` removes it, any other value sets it present.
