there are some syntax errors in your code. the part from <h2> to <a...... should be nested within a section element. Something like : <section>
//html elements go here… </section>
In the previous step, you nested all the elements within the main element in a section element :
That is the whole section element, it begins with an opening tag : <section> and ends with a closing tag : </section>.
Now, add another section element just after/below it, which means the opening tag of the new section element should be after the closing tag of the pevious section element
You need to add a new section under this exist section
<section>
<h2>Cat Photos</h2>
<!-- TODO: Add link to cat photos -->

<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>
</section>
and this is your code, what you did is you put a section inside another section
<section>
