This is the code that I have so far:

  h2 {
    color: blue;

  <p>Click here to view more <a href="#">cat photos</a>.</p>

  <a href="#"><img src="" alt="A cute orange cat lying on its back."></a>

    <p>Things cats love:</p>
      <li>cat nip</li>
      <li>laser pointers</li>

      <li>other cats</li>

Challenge: Use CSS Selectors to Style Elements

Link to the challenge:

Are you using a dark mode extension? If so, this can cause the tests to fail.

That’s was the reason @Roma I’m using a dark mode extension that helps my eyes and I didn’t know that could be an option that cause the tests to fail.

Thanks for the help!
