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

Posted by Jonathan Whittle

I've found no working solution and no previous videos are unhelpful.

The challenge asks to select every <a> under the <nav> element in the index.html file. It doesn't appear that I can alter the html and it still count, nor does any of my code work. Can anyone explain how to do this?

js/app.js 
let navigationLinks = document.getElementsByTagName('a:nth-child(3n)');
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">

Hi Jonathan

Try document.querySelectorAll('nav a'); when defining the navigationLinks variable.

Let me know how it goes!

It worked! Thanks for your reply. I thought I had tried that earlier to no avail. But I must have had something different.
