Can't get the list items that the exercise is requesting.

I'm struggling with this section. Any light on how to proceed?!

js/app.js 
let navigationLinks = document.getElementsByTagName("li")[0, 1, 2];
let galleryLinks;
let footerImages;

You don't need to do any indexing here, since the instructions ask for the entire collection. But you also have some issues with the selector:

  • the instructions ask for links, but a link is represented by an "a" element ("li" would be list item)
  • the instructions ask for "links in the nav element" which would require a descendant selector or a function chain
  • a descendant selector can be easily constructed by separating the container from the target with a space

Thanks Steven. I still don't get it (sometimes it takes me time). Can you post how the code would be so I can get it better? Again, thanks!

I think you'll have a better learning experience if you resolve it yourself. But if you apply the hints and still don't pass the challenge, repost the new code and perhaps I can give you another hint that will get you the rest of the way.
