How to use querySelectorAll or getElementsByTagName. Gap in understanding somewhere.

I'm misunderstanding how to access specific <li> tags nested within a <nav> tag in this problem. I've watched all of the videos twice, and did not see a solution. Could somebody please explain how to get to these? Thanks.

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

This function allows CSS-style selectors, so to target one tag type inside another you can use a "descendant selector", which is the outer tag and the inner tag separated by a space.

But also note that the challenge is asking for links (a), not list items (li), inside the nav element.

Steven Parker , hey thanks man! My brain was reading link and thinking list. Maybe I need a nap.

Anyhoo, thanks for answering my original question AND for guiding me in the right direction to complete the exercise. I did finally figure it out.

Happy to help. And FYI, getting "li" confused with "link" is a very common issue, based on other questions in this forum!
