Tell us what’s happening:

Your code so far

<style>
  .red-text {
    color: red;
  }
  .p{font-size=16px;}
</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> Purr jump eat the grass rip the couch scratched sunbathe, shed everywhere rip the couch sleep in the sink fluffy fur catnip scratched.</p>```

Your error is likely coming from this line. Try to find the syntax error here where you’re assigning the 16px value.

Good luck!!
