Can't figure this thing out

Tell us what’s happening:
I can’t figure out how to nest the submit cat photo thing in the form part

Your code so far

<link href="" rel="stylesheet" type="text/css">
  .red-text {
    color: red;

  h2 {
    font-family: Lobster, Monospace;

  p {
    font-size: 16px;
    font-family: Monospace;

  .thick-green-border {
    border-color: green;
    border-width: 10px;
    border-style: solid;
    border-radius: 50%;

  .smaller-image {
    width: 100px;

<h2 class="red-text">CatPhotoApp</h2>

<p>Click here for <a href="#">cat photos</a>.</p>

<a href="#"><img class="smaller-image thick-green-border" alt="A cute orange cat lying on its back. " src=""></a>

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

Link to the challenge:

Put the <input> element between the <form> tags.

The text field looks like:

<input type="text" placeholder="cat photo URL">

When the instructions say “nest”, it means put something in between tags. For example, if I wanted to nest the following h1 element:

<h1>Hello World!</h1>

inside a div element with id=“message”, I would do the following:

<div id="message">
  <h1>Hello World!</h1>

You just need to nest the text field inside the form tags as specified in the instructions and example.
