    Every element in Bulma is <strong>mobile-first</strong> and optimizes for <strong>vertical reading</strong>, so by default on mobile:

  <ul>
    <li><code>columns</code> are stacked vertically</li>
    <li>the <code>level</code> component will show its children stacked vertically</li>
    <li>the <code>nav</code> menu will be hidden</li>
  </ul>
  <p>You can however enforce the <strong>horizontal</strong> layout for both <code>columns</code> or <code>level</code> by appending the <code>is-mobile</code> modifier.</p>
