How do I get it to select the li of the ul in the nav class?

I can't seem to get the querySelectorAll() method to select all of the li inside the nav tag/class. Can anyone help?

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

Hi there! Your syntax is just fine, but you're attempting to select something that doesn't exist. You are trying to get the unordered list with the class "nav". But there is no such list in the HTML. And then you're trying to select the list items from that.

But the challenge is asking for you to select the links from the nav element. We make a link by using an anchor element or <a> tag. Also, remember that an element and a class are not the same thing.

This is how I did it:

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

This selects all the links (anchor elements) inside the nav element and returns them as a collection which is assigned to navigationLinks.

Hope this helps! :sparkles:
