尝试添加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(); 
          } 
         });
