Learn HTML by Building a Cat Photo App - Step 17

Within the second section element, add a new h2 element with the text Cat Lists.

I don’t understand where I have a mistake

<html>
<body>
  <h1>CatPhotoApp</h1>
  <main>
    <section>
      <h2>Cat Photos</h2>
      <!-- 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>
    </section>
    <section>
   <h2>Cat Lists.</h2>
    </section>
  </main>
</body>

I know it can be hard to tell, but you don’t want to include the period at the end of “Cat Lists”. The dark background in the instructions stops just before the period.

In general, you probably won’t include a period most of the time, so try removing the period first if you have trouble again.
