I don't know why they are telling me this: Your section element should have a closing tag. Closing tags have a / just after the < character

Tell us what’s happening:

Remember, an element has both an opening and closing tag (except for a few self-closing elements). So when you add a new element after an existing element that means to add the new element after the existing element’s closing tag.

tenes un <section> sin cerrar
fijate que debajo de main, abriste un section, después otro dentro del mismo, y solo cerraste uno, puede ser?

You have 3 section tags. 2 at the top and one with a closing slash at the end.
Remove one of the tags at the top and you’re good to go.
