title: Auto-size dynamic text to fill fixed size container
body: <p>I need to display user entered text into a fixed size div.  What i want is for the font size to be automatically adjusted so that the text fills the box as much as possible.</p>
  
  <p>So - If the div is 400px x 300px.  If someone enters ABC then it's really big font.  If they enter a paragraph, then it would be a tiny font.</p>
  
  <p>I'd probably want to start with a maximum font size - maybe 32px, and while the text is too big to fit the container, shrink the font size until it fits.</p>
