I have totally failed to get things right

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>
<main>
<p class="red-text">Click here to view more <a href="#">cat photos</a>.</p>

<a href="#"><img src="https://bit.ly/fcc-relaxing-cat" alt="A cute orange cat lying on its back."></a>

<div>
  <p>Things cats love:</p>
  <ul>
    <li>cat nip</li>
    <li>laser pointers</li>
    <li>lasagna</li>
  </ul>
  <p>Top 3 things cats hate:</p>
  <ol>
    <li>flea treatment</li>
    <li>thunder</li>
    <li>other cats</li>
  </ol>
</div>

<form action="https://freecatphotoapp.com/submit-cat-photo">
  <label><input type="radio" name="indoor-outdoor" checked> Indoor</label>
  <label><input type="radio" name="indoor-outdoor"> Outdoor</label><br>

Challenge: Change the Font Size of an Element

Link to the challenge:
https://www.freecodecamp.org/learn/responsive-web-design/basic-css/change-the-font-size-of-an-element

p{font-size:16px}

should be

p {font-size: 16px ; }

the semicolon is important

other than that, what do the tests say, what’s your question?
