title: Font-size is set to EM but doesn't scale up for tablet?
body: <p>I've been converting <a href="http://www.murraysworld.com/forum/" rel="nofollow">my forum</a> to responsive design using Bootstrap but I', seriously struggling with typography. Even though the font is in EM, on tablet devices, the font size ends up looking a lot smaller than it does on desktop.</p>
  
  <p>So I'm having to mess around with media queries to increase the font-size for smaller devices. And it's a struggle. Have I done something wrong here?</p>
