Returns a new MediaQueryList object representing the parsed results of the specified media query string.


mql = window.matchMedia(mediaQueryString)

where mediaQueryString is a string representing the media query for which to return a new MediaQueryList object.


if (window.matchMedia("(min-width: 400px)").matches) {
  /* the viewport is at least 400 pixels wide */
} else {
  /* the viewport is less than 400 pixels wide */

This code lets you handle things differently when the window is very narrow.

See Using media queries from code for additional examples.
