selecting descendent elements from the DOM.

Just having an issue identifying the 3 list items (li) that reside under nav. I was sure this would work and it does not.

document.querySelectorAll('nav li')

also tried

document.querySelectorAll('nav ul li')
js/app.js 
let navigationLinks = document.getElementsByTagName('nav ul li');
let galleryLinks;
let footerImages;
index.html
