title: CSS, select label with ending "*:"
body: <p>Is it somehow possible, via CSS, to select labels which contains *: at the end?</p>
  
  <p>Explained more deeply, as requested:</p>
  
  <p>Sorry, thought it was clear enough. I have a html-label-element ... which can contain *: at the end, for example: This is required*:. I would like to color those red.</p>
