How do you select all links inside the <nav> element and assign them to the variable navigationLinks?

I watched the descendants' video and tried using document.querySelectorAll('nav ul'); but get an error. Also tried 'nav li'. This is a tricky challenge for those who don't know CSS...

js/app.js 
let navigationLinks = document.querySelectorAll('nav ul');
let galleryLinks;
let footerImages;
index.html 
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Nick Pettit | Designer</title>
    <link rel="stylesheet" href="css/normalize.css">
    <link href='http://fonts.googleapis.com/css?family=Changa+One|Open+Sans:400italic,700italic,400,700,800' rel='stylesheet' type='text/css'>
    <link rel="stylesheet" href="css/main.css">
    <link rel="stylesheet" href="css/responsive.css">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

  <body>
    <header>
      <a href="index.html" id="logo">

      </a>

          <li><a href="about.html">About</a></li>
          <li><a href="contact.html">Contact</a></li>
        </ul>
      </nav>
    </header>
    <div id="wrapper">
      <section>
        <ul id="gallery">

You need to select all "Links" inside nav. The HTML tag for links is "<a>" .

This is the code you need to select all links inside <nav>:

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

to add to what Dimitar Dimitrov said, <a> is links (technically known as an anchor tag, hence the a), <li> stands for list item and <ul> stands for unordered list.

While in your case it would indeed select all the links because they are grandchild elements of the unordered list, and child elements of the list items, that's not exactly what was asked.

Those are html tags by the way, not css. Although you can reference them with css selectors.
