Remember you can use multiple selectors to target specific items on a page. So as an example, that navigation LIs that you're grabbing on that first line of your app.js. To get JUST those LIs, you can be more specific with your selector by passing 'nav li' to the querySelectorAll() method. That way you grab JUST the LI elements that are found inside of a NAV element.

Along those same lines you can couple different selectors, like trying to find all the LIs inside of an element with the ID of #gallery (i.e.: "#gallery li").

If you're still hung up, don't hesitate to rewatch videos! There are some that I've had to go back and watch multiple times before the concepts finally sink in! Good luck! ;)
