I am making a plugin for form validation as practice, but for some reason after I create a h2 element and try to set it's attribute, it is not working. Here is the code

    var testing = function(regex, value, error_msg, error_msg_field_id){

        var pattern = new RegExp(regex);

        if (!pattern.test(value)){

            var ele = document.createElement(H2);

            var node = document.createTextNode(error_msg);

            ele.setAttribute('style', 'color:white');

            alert(hi);

            jQuery(error_msg_field_id).append(node);

        }

    }

the text appears with no problem, but it is not in white color. This make no sense at all to me
