title: Center content vertically on Vuetify
body: <p>Is there a way to center content vertically in Vuetify?</p>
  
  <p>With the <code>text-xs-center</code> helper class, the content gets centered horizontally only:</p>
  
  <pre><code>&lt;v-container grid-list-md text-xs-center&gt;
    &lt;v-layout row wrap&gt;
       &lt;v-flex xs12&gt;
         Hello
       &lt;/v-flex&gt;
    &lt;/v-layout&gt;
  </code></pre>
  
  <p></p>
  
  <p>From the <a href="https://vuetifyjs.com/en/layout/grid-lists" rel="noreferrer">API</a>, I tested some other helper classes such as <code>align-content-center</code> but did not achieve the result.</p>
