See how you have all your elements that come after the opening main tag? Then you have the closing main tag after all the elements? All those elements are considered to be nested in your main element because they come between your opening and closing main tags. You do the same thing with the section element, and the elements that need to be nested in your section
Theres an example in the code I shared in my original post. Look how things are between the <main> and </main> thats nesting. Now look at what the directions say
“Take your h2 , comment, p , and anchor (a ) elements and nest them in a section element.”
So where would you put your opening section tag, and where would you put your closing tag?
