Totally Stuck

Don't really get what this challenge is looking for me to do. I have tried querySelectorAll, I've tried adding classes to the links I wish to use as well as trying getElementById and none return what it is looking for.

js/app.js 
let navigationLinks = document.querySelectorAll('a')[1, 2, 3];
let galleryLinks;
let footerImages;
index.html 
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">

Your syntax is incorrect for selecting elements. Drop the array with 1,2,3 and your code will begin selecting elements.

However it will select too many elements so you will need to add nav into your selection to narrow down how many a's are selected.

So would I write document.querySelectorAll("nav a"); or is there a different way to select children elements?
