Create a form Element:
What should I do??? I tried to use it on Chrome, Explore, Edge…but nothing.
I don’t know why this code is wrong :

  <form action="/submit-cat-photo">


<h2>CatPhotoApp</h2>
<main>
<p>Click here to view more <a href="#">cat photos</a>.</p>

<a href="#"><img src="https://www.bit.ly/fcc-relaxing-cat" alt="A cute orange cat lying on its back."></a>

<p>Things cats love:</p>
<ul>
  <li>cat nip</li>
  <li>laser pointers</li>
  <li>lasagna</li>
</ul>
<p>Top 3 things cats hate:</p>
<ol>
  <li>flea treatment</li>
  <li>thunder</li>
  <li>other cats</li>
</ol>
<form action="/submit-cat-photo">
  <input type="text" placeholder="cat photo URL">
</form>
</main>

The failing message should help you. It says
Your form should have an action attribute which is set to https://www.freecatphotoapp.com/submit-cat-photo

Your action attribute is incorrect
