MediaQueryList class
A object stores information on a media query applied to a
document, with support for both immediate and event-driven
matching against the state of the document.
You can create a by calling matchMedia() on the window
object. The resulting object handles sending notifications to
listeners when the media query state changes (i.e. when the media
query test starts or stops evaluating to true).
This is very useful for adaptive design, since this makes it
possible to observe a document to detect when its media queries
change, instead of polling the values periodically, and allows
you to programmatically make changes to a document based on media
query status.
