The instructions ask you to "select all links inside the <nav> element" They also give you this good hint: "Use a descendant selector ...".

A "descendant selector" is a combination of a selector for a container followed by the selector for the actual target, separated by a space. And remember that links are implemented using anchor (a) elements.

I'll bet you can get it now. :wink:

Sorry, but It's still unclear for me. I tried before let navigationLinks= document.querySelectorAll("nav li"); but It's uncorrect too :/

Good deal. Yes, links are "a". An "li" is a list item. :wink:
