Basic CSS: Use Attribute Selectors to Style Elements

Exercise: “Using the type attribute selector, try to give the checkboxes in CatPhotoApp a top margin of 10px and a bottom margin of 15px.” For some reason, it isn’t accepting my code…

<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;

   input[type='checkbox'] {

<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 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>

Write the code in single property like this.

margin: 10px 0 15px 0;

I copy pasted your code and it didn’t work, after that I resetted the challenge and simply typed the same thing as you’ve typed:

  input[type='checkbox'] {
    margin-top: 10px;
    margin-bottom: 15px;

And it worked.


I think the difference is the space after the colon (:).

hey tev97,
i checked your coding, you have done all thing right only the mistake is missing of a bracket in css .

check your code here that

 .silver-background {
    background-color: silver;

   input[type='checkbox'] {

you forgot to put ending curly bracket for .silver-background just close it.

.silver-background {
    background-color: silver;

now enjoy,
click it as solution, if it solved your issue

mine not working. i tried to reset the code and to change the browser to no avail.

Exactly the same happened to me, i spent 30 minutes coping. pasting, deleting and re-writing the same code over and over, and then i stumbled upon your post and i did exactly the same, i copied the code given and pasted it and my challenge past.
so, Thank you very much. :smile:

And may i ask a question like a freshman?
There was no word “input” before the square brackets with the attribute in the example. And it worked brilliantly.
Does it really so matter?
