  <p>I want to achieve this structure by using grid-column and grid, but in my case columns 5 and 6 don't fill all width, how can fix it?</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>.parent {
    display: grid;
    grid-template-columns: auto auto;
    grid-column-gap: 16px;
  }
  
  .child {
    height: 50px;
    background: rgb(82, 185, 15);
    display: flex;
    align-items: center;
    justify-content: center;
  }
  
  .gridColumn {
    grid-column: 1;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="parent"&gt;
   &lt;div class="child"&gt;1&lt;/div&gt;
   &lt;div class="child"&gt;2&lt;/div&gt;
   &lt;div class="child"&gt;3&lt;/div&gt;
   &lt;div class="child"&gt;4&lt;/div&gt;
   &lt;div class="child gridColumn" &gt;
    5
   &lt;/div&gt;
   &lt;div class="child gridColumn"&gt;
   6
   &lt;/div&gt;
   &lt;div class="child gridColumn"&gt;
   7
   &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
