function(tagName, options, children) {
        var e = env.doc.createElement(tagName);
        utils.forEach(options || {}, function(value, name) {
            if (name == 'style') { e.style.cssText = value; }
            else if (name == 'html') { e.innerHTML = value; }
            else if (name == 'className') { e.className = value; }
            else { e.setAttribute(name, value); }
        });
        children && utils.forEach(children, function(c) {
            e.appendChild(c);
        });
        return e;
