jquery validation styling code example

Example 1: how to change the color of error message in jquery validation

.error {
      color: red;
      background-color: #acf;
   }

highlight: function(element) {
    $(element).parent().addClass('has-error');
  },
  unhighlight: function(element) {
    $(element).parent().removeClass('has-error');
  },
