let navigationLinks = document.querySelectorAll('.selected');
let galleryLinks;
let footerImages;
index.html

Hi youngjin ha ,

The question is asking you to select the anchor (<a>) elements inside the navigation (<nav>). To do this you can use the following code:

let navigationLinks = document.querySelectorAll('nav li a');

This query is searching for nav > list items > anchor tags.

Hope that helps.
