matchMedia() polyfill

This fork of the matchMedia polyfill was created for the sole reason of publishing the latest version to npm (see issue #82 in the original repository). It will be deprecated once the issue is resolved.

test whether a CSS media type or media query applies

• Authors: Scott Jehl, Paul Irish, Nicholas Zakas
• Spec: dev.w3.org/csswg/cssom-view/#dom-window-matchmedia
• Native support: Chrome since m10, Firefox since 6, and Safari since 5.1

How about resizing the browser?

Paul Hayes tackled this using CSS transitions and their transitionEnd event

His code: https://github.com/fofr/matchMedia.js -- though currently it doesnt support IE6-9, since they dont have transitions, obviously. :)

Usage

test 'tv' media type

if (matchMedia('tv').matches) {
  // tv media type supported
}

test a mobile device media query

if (matchMedia('only screen and (max-width: 480px)').matches) {
  // smartphone/iphone... maybe run some small-screen related dom scripting?
}

test landscape orientation

if (matchMedia('all and (orientation:landscape)').matches) {
  // probably tablet in widescreen view
}

Used in:

• Respond.js
• FormFactor
• Modernizr
