unsure on how to select only the 3 links.

Unsure how to select only those 3 links. Assigned them all 3 classes and even tried to select by class name. still did not work.

js/app.js 
let navigationLinks = document.getElementsByClassName("navLinks");
let galleryLinks;
let footerImages;
index.html 
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Nick Pettit | Designer</title>

Hello!

You could use a css selector for that and try with:

let navigationLinks = document.querySelector(".navLinks, a");

Which will basically select all elements that have their class attribute "navLinks" and those who are anchor tags, or <a>.

Hope that helped!

Hi Wil. Based on the code you have posted, your solution is on the right lines. This is what I see in my devtools console.

navigationLinks

HTMLCollection(3)Ā [a.navLinks, a.navLinks, a.navLinks]
0: a.navLinks
1: a.navLinks
2: a.navLinks
length: 3
__proto__: HTMLCollection

However, you are tackling a Treehouse Challenge, and they don't expect you to be altering the index.html page by adding classes etc.. Instead, just by using the available tags, this solution will pick the specific 3 links out from the 8 links on the page. You are first selecting the nav element, then selecting all a tags that lie within it.

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