Tell us what’s happening:

   **Your code so far**

<!DOCTYPE html>
<html>
 <h1> websites are awesome!</h1>

</html>

   **Your browser information:**

User Agent is: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.1.3 Safari/605.1.15.

Your code passes for me. Sometimes this happens. Reload, clear your browser cache, try a different browser, reboot. If nothing works, just back out and go onto the next challenge.
