let navigationLinks = document.querySelectorAll('[nav],[ul]');
let galleryLinks; 
let footerImages;
index.html 
<!DOCTYPE html>

Hi Nas!

This passes all three:

let navigationLinks = document.querySelectorAll('nav a'); // Task 1
let galleryLinks = document.querySelectorAll('#gallery a'); // Task 2 
let footerImages = document.querySelectorAll('footer img'); // Task 3

Keep in mind a descendant selector is just two selectors (parent and child/nested) separated by a space.

'nav a' targets all anchor/link elements nested within the nav element.

And how deeply the child may be nested is irrelevant.

I hope that helps.

Stay safe and happy coding!
