Challenge: Learn HTML by Building a Cat Photo App - Step 1

Link to the challenge:

hi there, welcome to the forum.

You haven’t asked any question but it seems you have misunderstood the exercise.
An h1 element has 3 parts
<h1>the text in the middle</h1>

The opening tag is the first part and the third part is the matching closing tag.
In between is the 2nd part which is the “text” of the h1 element.
This text should be set to CatPhotoApp

So please reset this exercise and try to set the text to the value provided.
