You are on the right track with .querySelectorAll. You can use that method for all three steps in the challenge.

Try it again using .querySelectorAll and if you can't figure it out check out the bottom for the answer.

Don't forget to read each step closely to find out exactly what you are supposed to be assigning to the variables. For example, in Step 2 you should be looking for elements with an ID of "gallery" but the method you are trying to use is for classes not id's.

let navigationLinks = document.querySelectorAll("nav a");
let galleryLinks = document.querySelectorAll("#gallery a");
let footerImages = document.querySelectorAll("footer img");
