Here’s the solution guys:
< style>
h2 {color: blue;}
< /style>
< h2>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>
I had to make spaces inside tags to could show you the code itself, just remove the space and should be good.
