title: How to customize font size in Ionic Framework
body: <p>I'm using ionic framework (with cordova) to develop mobile apps.
  What I want to do is to increase the font size (in general in my app).</p>
  
  <p>I've seen that in the official documentation : <a href="http://ionicframework.com/tutorials/customizing-ionic-with-sass/">http://ionicframework.com/tutorials/customizing-ionic-with-sass/</a>.
  But I do not understand how to customize once sass is working.</p>
  
  <p>I'm working in a tabs-based App like that : <a href="http://forum.ionicframework.com/uploads/default/269/9934610f0a08b8d2.png">http://forum.ionicframework.com/uploads/default/269/9934610f0a08b8d2.png</a>
  I tried to manually add a class on the tab, but the result is not very clean... the text is cropped...</p>
  
  <p>Is there an official way to change the font-size ?</p>
