title: Styling the hint on a HTML5 input field using required attribute
body: <p>Is it possible to style the hint that appears on a HTML5 input field when using the required attribute. If you're not sure what I'm talking about click submit on this form without filling anything in. You should have a hint popup.</p>

  <p>I've checked the CSS source and couldn't see anything regarding the hint.</p>
  
  <p>I have found that styling the div element in a reset fashion affects how it appears. But I do not know how to target it specifically.</p>
  
  <p>Please note: I am NOT referring to a placeholder.</p>
  
  <p>Cheers,
  Thomas.</p>
