Click the “Reset All Code” button to start the challenge over fresh. Then only do exactly what the instructions tell you to do:
Add an h2 tag that says "CatPhotoApp" to create a second HTML element below your "Hello World" h1 element.
The only thing you should add is the h2 tag with the string "“CatPhotoApp” in it right below the existing h1 tag. The formatting is exactly the same except that instead of h1 you are using h2.
