If you Restart the step (by clicking on the Restart Step button) you will see that initially you were given this block of code:
<!-- TODO: Add link to cat photos -->
<p>Click here to view more <a target="_blank" href="https://freecatphotoapp.com">cat photos</a>.</p>
<a href="https://freecatphotoapp.com"><img src="https://cdn.freecodecamp.org/curriculum/cat-photo-app/relaxing-cat.jpg" alt="A cute orange cat lying on its back."></a>
Everything in this block is part of the section element. (so even the h2, p etc, they are all nested inside the section element).
So when you are asked to add something after the section element,
you must add it after this code block, and not in the middle of it.
(add a new line after the closing tag on the last line and add your code there)
