JavaScript JavaScript and the DOM (Retiring) Getting a Handle on the DOM Practice Selecting Elements

I am having trouble getting the elements found within nav, I wnat to know where in the video do we talk about this?

Why is it that there is such a big disconnect between this quiestion and what is being taught. I want to find out how I can get all the elements under <nav> the problem for lies inthe fact that even if I change the HTML code it still doesn't work because the question process doesn't save any changes to the HTML doc, I tried giving all the list items an ID. What should I do?

let navigationLinks = document.getElementById('nav');
let galleryLinks;
let footerImages;
<!DOCTYPE html>

Hello Wild,

I saw that updating the HTML won't work because somehow it doesn't save the changes. I also see in your code that you're targeting the <nav> element, you should target all the <a> elements that are descendants of the <nav> instead, the .getElementById() method won't work in this case because it targets only one unique element, not a set of elements, and to do this you must use a method that does that.

A way you can achieve this real quick is using the .querySelectorAll() method to target all the <a> elements that are descendants of the <nav> element (to target them you must use CSS syntax):

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

Hope this helps :)
