title: Getting the right font-size on every mobile device
body: <p>In my mobile app I use kind of big fonts for example:</p>
  
  <p><code>&lt;b style="font-size:100px; font-family:Segoe UI"&gt;text&lt;/b&gt;</code></p>
  
  <p>When I test it on my phone it looks great but on a smaller phone it's still the same size and it is too big.</p>
  
  <p>What css settings should I use to get the same size on every phone?</p>
