Ive been stuck for 3 days

I have been stuck on the question for 3 days now. I have rewatched the videos numerous times now. I can't seem to find a solution.

Here is what I try:

JavaScript: let navigationLinks = document.querySelectorAll("navLinks");

HTML: <nav class="navLinks"><ul><li></li><?ul></nav>

Thank you in advance for the help.

js/app.js 
let navigationLinks = document.querySelectorAll('navLinks:li');
let galleryLink;
let footerImages;
index.html

Think about CSS selectors.

You have a good idea using querySelectorAll, just remember that the selectors should be constructed as if you were using CSS. The instructions say "select all links in the nav element ". Since links are represented by "a" elements, then a descendant selector that would target only those in the "nav" element would be: "nav a".

Thank you very much. That worked and I can't believe I did not notice it. I don't really find the videos as informative in this situation as they should be. I am having difficulties on the second part of that challenge as well. Its odd because up until this point I really haven't had much trouble learning the syntax and how to properly "word things".

In the second part of the challenge it asks about the elements with the gallery id, I'm using this:

let galleryLink = document.queryselectorall("gallery");

I have even tried:

let gallerLink= document.queryselectorall("ul: gallery");

and it is not working. I don't seem to understand how to properly select things.

Any insight would be greatly appreciated as I seem to be stumped.

Thanks,

On the second task you are selecting the id=gallery links. When making selections, use a dot before class names and a # before ids. In this case the querySelectorAll("#gallery a").
