title: Foundation hide-for-small not working
body: <p>I am trying to use foundations <code>hide-for-small</code> class to hide my navbar on mobile. It doesn't appear to be having any affect. As far as I understand</p>
  
  <pre><code>&lt;h1 class="hide-for-small"&gt;Hidden on Mobile&lt;/h1&gt;
  </code></pre>
  
  <p>should show the element on my computer, but hide it on my iPhone.</p>
  
  <p>What am I missing?</p>
