title: How font-size em value work?
body: <p>Im using em font sizes, which is working fine for everywhere apart from the sidebar.</p>
  
  <p>In the main content the em size is great. If I copy this em size to the sidebar the text becomes larger.</p>
  
  <p>Im using a html/body size of 17px. Then 1.412em to get the size I would like. To see a live link of the sidebar font bigger go to this <a href="http://www.probablybest.co" rel="nofollow">link</a>. If you look at the twitter feed on the right sidebar you will see its using the same em but you view it a lot larger.</p>
