How do I use a JavaScript code by writing a selector that targets all <a> elements inside the <nav> element. 

<nav>
  <ul>
    <li><a href="index.html">Portfolio</a></li>
    <li><a href="about.html">About</a></li>
    <li><a href="contact.html">Contact</a></li>
  </ul>
</nav>

Complete the JavaScript code below by writing a selector that targets all <a> elements inside the <nav> element: 

var expectedLinks = document.querySelectorAll(" ");

Creating a "dependent selector" is the same as if you were doing it for CSS. You put the selector for the containing element first, followed by the selector for the target element, with a space in between.

Wow. I kept thinking I needed the child selector >. But now that makes sense since <li>'s aren't direct decedents of the <nav>. They're nested within the <ul>

Thank you! That was making my head spin.

Remember: container - then a space - then the target. So what have you tried?

"ul li" "ul li a" I can't quite see where I am going wrong here.
