The MediaList interface provides the abstraction of an ordered collection of media, without defining or constraining how this collection is implemented. An empty list is the same as a list that contains the medium "all".

The items in the MediaList are accessible via an integral index, starting from 0.

See also the Document Object Model (DOM) Level 2 Style Specification.
