How can I specify to get those 3 links and not the other ones

I try to add class or ID names to the the items in the html file but it doesn't update. Any way to select those 3 without altering the HTML code and using either .querySelectorAll or getElementsByTagName?

js/app.js 
let navigationLinks = document.getElementsByTagName('nav');
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">
  </head>
  <body>
    <header>
      <a href="index.html" id="logo">
        <h1>Nick Pettit</h1>
        <h2>Designer</h2>
      </a>
      <nav>
        <ul>
          <li><a href="index.html" class="selected">Portfolio</a></li>
          <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">
          <li>
            <a href="img/numbers-01.jpg">
              <img src="img/numbers-01.jpg" alt="">
              <p>Experimentation with color and texture.</p>
            </a>
          </li>
          <li>
            <a href="img/numbers-02.jpg">
              <img src="img/numbers-02.jpg" alt="">

            </a>
          </li>
        </ul>

      </footer>
    </div>
  <script src="js/app.js"></script>
  </body>

Hey Subraiz Ahmed! You can select elements by specificity. For example, they want you to grab the navigation links. So if you look at the HTML structure, you can see that the anchor elements are nested deep in the navigation element. In order to grab the anchor elements you need to specify it like so: nav ul li a. This will get you the 3 links in the main navigation.

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

Ohhh ok thank you for your help. I wasn't sure how could specify a tag within a tag.
