title: CSS Font Size Specifics
body: <p>I have a couple of specific questions about font size:</p>
  
  <ol>
  <li>Is pt (I.E. 12pt) standardized?  I think I read somewhere that pt = 1/72 of an inch.  However, the size of 24pt font in photoshop is significantly different from size 24pt font in css.</li>
  <li>What exactly does font-size determine? Is it a sort of unstandardized arbitrary description about letter size or does it actually refer to the specific height or width attribute of letters?</li>
  </ol>
  
  <p>Thanks Stack!</p>
