    console.log('Requesting ' + path + '... in progress');

    if (document.createStyleSheet) {
        try {
            console.log('Loading ' + path + '... in progress');

            document.createStyleSheet(path);
        } catch (e) {
            console.log('Failed dynamically loading stylesheet.');
        }
    } else {
        var css;

        css = document.createElement('link');
        css.rel = 'stylesheet';
        css.type = 'text/css';
        css.media = 'all';
        css.href = path;

        document.getElementsByTagName('head')[0].appendChild(css);
        console.log('Appending ' + path + ' to document head... success');
    }
}
