Just lost, poor explanation of topic...

Actually don't understand why this code return only one link... let galleryLinks = document.querySelectorAll("#gallery"); No explanation in video, page from MDN doesn't help.

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

Hi Ilia!

I guess you are stuck at the second challenge?

"Next, select all <a> elements inside the unordered list with the ID gallery and assign them to the variable galleryLinks.

If that's the case, then you forgot to add the "a" next to the "gallery", since it asks you to select all <a> elements inside the ul gallery. You selected the entire gallery, so all that is needed is an "a" next to the #gallery - let galleryLinks = document.querySelectorAll("#gallery a");

I hope this clarifies it for you, and feel free to ask if you need more help :)

Armin, Thank you so much for your help, everything works fine, when used document.querySelectorAll("#gallery") - received a message that it should be 2 objects not one, maybe that's why I'm confused Thx one more time for your help!!!

They should go over these in a little more detail all the different variations. Attribute selector, Pseudo-class and this Descendant Selector. I searched MDN and rewatched all the videos and teacher notes and still struggled to find a clear answer. or even adding a HINT to this question would have been super helpful.

Thank you Armin for the Help!
