I am stuck on the Practice selecting elements question 1.

I have tried query selector, and getElementsByTagName but not having any luck

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

Links are represented by anchor ("a") elements. But you don't want just links here, just those that are inside the nav element. So this might be a good place for querySelectorAll used with a descendant selector: "nav a".

Got it, thanks, I did not realize you could chain selectors

That's not actually "chaining". It's "combining", just like you might do when writing CSS.

Happy coding!
