AMDBodySizeDetect

http://adactio.com/journal/5429/

// Module given an id as I usually drop it in a main.js
// equivalent. It's hardly worth it's own file
// Returns a function so it can be called after DOMReady
define('mq', function() {
    return function() {
        return window.getComputedStyle(document.body,':after').getPropertyValue('content');
    }
});

// Usage

require(['mq'], function(mq) {
	if (mq() === 'phone') {
		// pow pow
	}
})
