title: Is sizing fonts using "em" still relevant?
body: <p>Those of you who use <em>em</em> when sizing fonts will know that they can be a headache when dealing with nested elements, and having to make the <em>px</em> -> <em>em</em> calculations (to ensure your design interpretation is correct @ 100%) consumes extra time.</p>
  
  <p>With these (admittedly minor) issues in mind, and given the recent progress the major browsers have made towards natively dealing with accessibility issues such as page scaling / zooming, is using <em>em</em> to size fonts still considered worthwhile? *</p>
  
  <p>*legacy browser (IE6) support excluded.</p>
