For this challenge, you only write JavaScript.

So don't make any changes to the HTML. But technically, the idea could work but the challenge wanted the links ("a" tags) selected but you applied the class to the list items ("li") instead.

So what you might want to do for solving the challenge is make use of querySelectorAll. It lets you pick items using selectors much like those for CSS. And since you want the links ("a") in the nav element, this could be a good place to use a descendant selector where you combine terms with a space.
