title: ghost text - how to have faint text in textbox
body: <p>I've an online form:</p>
  
  <p><a href="http://yoursdproperty.com/index.php?option=com_chronocontact&amp;Itemid=56" rel="nofollow noreferrer">http://yoursdproperty.com/index.php?option=com_chronocontact&amp;Itemid=56</a></p>
  
  <p>I would like to have some faint gray text there so that when the user clicks on it, it disappears</p>
  
  <p>exactly like in this StackOverflow form where in the title of the question it says "what's your programming question, be descriptive?"</p>
  
  <p>what is the simplest way to implement this?</p>
