css-feature-detection.js

define(function() {

    /**
     * CSS feature detection
     * @param {String} property
     * @returns {String}
     */
    return function(property) {
        var i, len, prop;
        var support = '';
        var prefixes = ['ms', 'moz', 'webkit'];
        var temp = document.createElement('div');

        prop = property.toLowerCase();
        if (prop in temp.style) {
            support = prop;
        }
        else {
            for (i = 0, len = prefixes.length; i < len; i++) {
                prop = prefixes[i] + property;
                if (prop in temp.style) {
                    support = prop;
                    break;
                }
            }
        }

        return support;
    };

});
