title: Is it possible to resize text to fit a fixed size div?
body: <p>This seems like a pretty natural use case to me, though I haven't been able to find anything on it:</p>
  
  <p>Say I have a fixed-width div that is dynamically populated with some number. What's the best way to ensure that numbers with more digits take smaller font sizes such that they fit nicely into that fixed width? Is there some CSS property for this, or do I have to resort to Javascript hackage?</p>
