Learn HTML by Building a Cat Photo App - Step 1

The error I receive on this application is:” You appear to be using a browser extension that is modifying the page. Be sure to turn off all browser extensions.”

I have no active extension when I checked. And I’m entering the text the program asks for but it’s still not correct.

Your code so far

<html>
  <body>
    <h1>CatPhotoApp</h1>
  </body>
</html>
