I cant understand how to wright this code

Describe your issue in detail here.

Step 6

In the previous step, you nested the h2 element, comment, and p element within the main element. A nested element is a child of its parent element. It should be indented two more spaces than its parent element to improve readability, like this:

<ul> 
  <li> Child Element 1 </li>
  <li> Child Element 2 </li>
</ul>

Add two spaces in front of the three child elements of main so your HTML is more readable

  **Your code so far**
<html>
<body>
  <h1>CatPhotoApp</h1>
  <main>        
        <h2>Cat Photos</h2>

  <!-- TODO: Add link to cat photos -->
  <p>Click here to view more cat photos.</p>
  </main>
</body>
</html>
