title: Ionic center text vertically and horizontally on screen
body: <p>I'm trying to vertically align my text on my screen. I've read through <a href="http://ionicframework.com/docs/components/#grid-vertically-align">the docs</a> on how to do this. But I'm still not having any luck. This is my code:</p>
  
  <pre><code>&lt;div class="row"&gt;
    &lt;div class="col col-center text-center"&gt;
      &lt;h4 class="gray"&gt;This text is in the center of the screen&lt;/h4&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
