My code:

</style>

 <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>

@callumrichards1886 There is a weird character before your [_].red-text {color:red;}. Try to remove that
