嘗試添加errorClass:'error',

$("#contact-form").validate({
                            rules: {
                                name: "required",
                                subject: "required",
                                errorClass:'error',
                                email: {
                                    required: true,
                                    email: true
                                },
                                comment: "required"
                            },
                            messages: {
                                name: "Please enter your Name",
                                subject: "Please enter a Subject",
                                email: "Please enter a valid Email Address",
                                comment: "Please enter your Message",

                            },
                            submitHandler: function(form) {
                                form.submit();
                            }
                        });
