I am using document.querySelectorAll('.slected') and added the class to the other two links within the nav element.

js/app.js
let navigationLinks = document.querySelectorAll('.selected');
let galleryLinks;
let footerImages;

Adding the class to the other two links isn't sufficient here, as that generally has other implications for the webpage beyond just the JavaScript being able to reference them directly (such as CSS, for example). Instead, you need to complete this challenge without modifying the HTML at all, and directly select all the a elements in the nav element

I already tried docment.querySelectorAll('nav') and docment.querySelectorAll('[nav]') and docment.querySelectorAll('nav : nth-child(all)')

Pay attention closely to what the challenge is asking here. It's not asking for all the elements in the nav element. It's asking for all the links within the nav element. Links are a elements, so that'll need to be part of your selector, but you're otherwise on the right track with the first try in this list

Any suggestions? I get syntax error when using nth-child.

how deep are the links within the nav element? How would you select them using CSS?

I put ids on all the links and tried using querySelectorAll and it didnt work.

I have put ids on everything, and it stil didnt work. I tried selecting the nav woth querySelector and the wrting navigationLinks = document.getElementsByTagName('a'); and it didnt work.
