title: Can you you show a grey hint in an HTML text box with CSS alone?
body: <p>You see these text input boxes from time to time on the web: a grey label is shown inside the box, but once you type there, the grey text disappears. This page even has one: the "Title" field behaves exactly like that.</p>
  
  <p>So, questions:</p>
  
  <ol>
  <li><p>Is there a standard term for this? I'm really struggling to find anything on google</p></li>
  <li><p>Can it be done with just CSS?</p></li>
  <li><p>Failing that, can it be done with localised JavaScript? (ie, code just within the  tag, not in the HTML header).</p></li>
  </ol>
