public interface MediaList
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.
