Return Elements Using CSS Selectors

https://teamtreehouse.com/library/javascript-and-the-dom-3/getting-a-handle-on-the-dom/return-elements-using-css-selectors

I keep getting error messages no matter what approach I use to answer the first of these objectives in the link above.

Here's the question:

"In this challenge, you're going to select various elements from index.html. First, select all <a> elements inside the <nav> element and assign them to the variable navigationLinks. (HINT: Use a descendant selector to match elements that are descendants of an element.) "

After many different attempts, this is the closest I can get:

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

Here's the error message I get:

"Bummer: Make sure that you're selecting 3 links. It looks like you've selected 1 links."

What am I doing wrong?

You haven't actually selected any links, but the response is correct that you selected just one element.

The instructions ask you to "select all <a> elements inside the <nav> element", but what that code does is to select all <nav> elements (and there is only one). To select elements that are inside another element you can use a descendant selector, which is the container selector combined with the target selector using a space. So to select all <a> elements inside the <nav> your selector would be "nav a".
