title: How do I make the first grid item span 100%?
body: <p>I have the following for desktop, which creates 4 equal columns all at 25%. </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.footer-inner {
    display: grid;
    grid-template-columns: repeat(4, 1fr);
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="footer-inner"&gt;
    &lt;div&gt;One&lt;/div&gt;
    &lt;div&gt;Two&lt;/div&gt;
    &lt;div&gt;Three&lt;/div&gt;
    &lt;div&gt;Four&lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>However, how can I resize these in a media query to make the first column go 100% and the rest of the columns naturally wrap underneath and now be 33.333% still using CSS grids?</p>
  
  <pre><code>.footer-inner {
    display: grid;
    grid-template-columns: 100% 1fr 1fr 1fr; 
    /* AND THIS */
    grid-template-columns: 100% 33.333% 33.333% 33.333%;
  }
  </code></pre>
