I gave for the 3 <li> the class navLI, so why document.getElementsByClassName("navLi"); doesn't work?

I'm trying to get the 3 option of the nav, why I cannot take them if I create one class to select them?

js/app.js 
let navigationLinks = document.getElementsByClassName("navLi");
let galleryLinks;
let footerImages;

This challenge is a little tricky because it requires some more advanced knowledge of how to select CSS selectors.

It is possible to select the link elements inside <nav> without giving those <li> elements class names. Here is how how I did it:

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

The above coding is selecting the elements inside nav, inside ul, inside li, inside a. So this: ('nav > ul > li > a'). You can read more about different ways to use selectors here: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors
