       applyCss: function (css) {
            var style = document.createElement('style');
            style.type = 'text/css';

            try {
                style.appendChild(document.createTextNode(css));
            } catch (e) {
                if (style.styleSheet) {
                    style.styleSheet.cssText = css;
                }
            }

            document.body.appendChild(style);
        },
