title: Adding <sup> asterisk to placeholder, or a nice way to mark required fields via placeholder
body: <p>I'm looking for a way to style the asterisk in the placeholder. </p>
  
  <p>Plain text like this in placeholder does not satisfy me:</p>
  
  <blockquote>
    <p>Your e-mail*</p>
  </blockquote>
  
  <p>Note that the placeholder text is variable, so static background will not play the trick</p>
