The class used for the validation messages is .mx-validation-message
You can alter the .mx-validation-message class as per your need. Incase you do not want to show the message, then you can add style
Make sure you do not change the core class, instead update it using your custom sass or css files.
you are awesome. it just worked perfectly per the requirement. Thank you.
Another question on the same. it hides the feedback message everywhere i apply the validation. I want to hide it on certain pages or certain widgets only. Can i achieve that?
