Selected tag name elements.

I'm probably overthinking this one or grabbing at the wrong code, but I need help with this one. Thank you!

js/app.js 
let navigationLinks = document.getElementsByTagName('nav'); || document.querySelectorAll('nav');
let galleryLinks;
let footerImages;

Hey David,

You need to select all elements inside the nav element, you can do that with the querySelectorAll method.

document.querySelectorAll('nav a'); //will select all a elements inside the nav element.

You don't want the nav element itself, but the links (a's) it contains.

You might try using a descendant selector with querySelectorAll.

I'm assuming you realize the code above is not proper syntax and you placed the "||" symbol just to show that you couldn't decide which of those methods to use.

Haha yes I realize that about the syntax. Just wanted to show the two selectors I thought were right. Thank you!
