CSS class, element not turning red

My h2 element isn’t turning red:

Your code so far

  h2 {
    color: blue;

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

<p>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>
