Font Family of an Element Code Doesn't Work

Hi there!
I’m totally new to ‘coding stuff’. So far so good, until I’m stuck with this problem. I have tried to follow the hint on the website, but it doesn’t work. Please help.

Your code so far

<style>
  .red-text {
    color: red;
  }

  p {
    font-size: 16px; 
    font-family: Monospace;
  }
</style>

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

<p class="red-text">Kitty ipsum dolor sit amet, shed everywhere shed everywhere stretching attack your ankles chase the red dot, hairball run catnip eat the grass sniff.</p>
<p class="red-text">Purr jump eat the grass rip the couch scratched sunbathe, shed everywhere rip the couch sleep in the sink fluffy fur catnip scratched.</p>

Thank you!
I found out that I made another mistake like:
.smaller-image {
width: 100 px;

I added space after 100. Therefore, the second task wasn’t complete as well.
