You're pretty close here.

But there's no element with an id of "navigation". Besides, you can simplify your selector a good bit.

The instructions asked for "all links in the nav element", and you can translate that directly into a descendent selector ("nav a").

For problems like this, I hope you don't mind but I'm more for giving clues than the answer as I helps make the solution really stick.

In your code: let navigationLinks= document.querySelectorAll('#navigation>li>a');

You're saying: "give me all the anchor tags, that are in list elements, that have an id of "navigation".

So in your index.html file, your links should reflect that statement.

Hope that helps, and I'm more than happy to continue helping you if that seems too cryptic.

What it actually translates into is:
give me all the anchor tags, that are in list elements, that are inside some element with an id of "navigation"

That was so simple. I was fetching for li instead of anchor tag. Thank you.
