Use an id Attribute to Style an Element2

Tell us what’s happening: how do i do this “Your form element should have the background-color of green” without adding a style or class to the form

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;

  .silver-background {
    background-color: silver;

<h2 class="red-text">CatPhotoApp</h2>
  <p class="red-text">Click here to view more <a href="#">cat photos</a>.</p>
  <a href="#"><img class="smaller-image thick-green-border" src="" alt="A cute orange cat lying on its back."></a>
  <div class="silver-background">
    <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>
  <form style="background-color" action="/submit-cat-photo" id="cat-photo-form">
    <label><input type="radio" #name="indoor-outdoor" checked> Indoor</label>
    <label><input type="radio" #name="indoor-outdoor"> Outdoor</label><br>
    <label><input type="checkbox" #name="personality" checked> Loving</label>
    <label><input type="checkbox" #name="personality"> Lazy</label>
    <label><input type="checkbox" #name="personality"> Energetic</label><br>
    <input type="text" placeholder="cat photo URL" required>
    <button type="submit">Submit</button>

Link to the challenge:

Use this id inside the form element to give a green color background

How do i do that, I have tried doing it

Like you did for classes where you had "." before the classname, here you need to call the id using # symbol before the id name

Use this code inside your style tag. It targets the id and styles it.
Solution below:

background-color: green;

I have used it, but how do i add it to the Id attributes?

You have already added the id attribute, all you need is to call using the # in your style

Please how do i do that?

You have id=“cat-photo-form” in your form tag,
id’s are called using # and classes are called using dot

#cat-photo-form { 
add the style here; 

You can refer this to see how to use classes and id’s
