As most things in programming, there's more than one way so you have choices. You specifically want the links ("a" elements) inside the "nav" element, so you could chain two selector methods or use just one that allows a more complex selector.

The second choice can be done using the "querySelectorAll" method and provide a CSS-style descendant selector as the argument.

Thanks, I had no idea about descendant selectors. I don't remember learning about these when doing CSS here. Was a while ago though.

A "descendant selector" is just the container and the target separated by a space.
