How can I leave a message after input

Hi, how can I leave a message after input?
or under the label
the message is overlapping

I’m using jquery to do a custom validation
follow my code below:

<script>
  
$(document).ready(function() {
    $('form').validate({
    	rules: {
          nome_completo: {
        	maxlength: 10,
            minlength: 5,
          }
        },
        errorPlacement: function(error, element) {
           error.insertBefore(element);
        }
    })
})
  
</script>

i tried using insertBefore but it didn’t work
