The challenge asks for "all links in the nav element". But links are represented by "a" tags ("li" is for list items).

Also, if you've already select the nav element, your next step would only need to select the links (you would not need a combined selector).

Hey! but as the <a> tags are inside <li>, shouldnt just selecting document.querySelectorAll('nav li'); work ?

You're right that the "li" is a parent of the link, but the challenge is looking for the links themselves.
