These are the current validation rules and messages that I have applied. The error messages work however I would like the text to be red and bold. How and where do I style the error messages? 

$("#payment-form").validate({

    rules: {

        email: {

            required: true,

            email: true

        },

        password: {

            required: true,

            minlength: 8

        },

        password_confirm: {

            required: true,

            minlength: 8,

            equalTo: "#password"

      }

    },

    messages: {

        email: "Please enter a valid email address",

        password: {

          required: "Please provide a password",

          minlength: "Your password must be at least 8 characters long",

        },

        password_confirm: {

          required: "Please provide a password",

          minlength: "Your password must be at least 8 characters long",

          equalTo: "Please enter the same password as above"

        }

    }

  });
