Challenge: Step 16

Link to the challenge:

You’ve nested one section inside the other. If we were talking about divs, it would be like:

<div>
  <div>
    ...
  </div>
</div>

That is not a div after a div, that is a div inside a div. For the former, you would need:

<div>
  ...
</div>
<div>
</div>
