There is no reason why task 1 should no longer work. Your Challenge Task app is flawed.

I would like to continue learning on TeamTreeHouse but now I'll have wait until the next day I have free time because there is no way to skip a broken challenge.

js/app.js 
let navigationLinks = document.querySelectorAll("nav > ul > li > a");
let container1 = document.querySelector("#gallery");
let footerImages = document.querySelectorAll("footer > a > img");
let galleryLinks = container.getElementsByTagName("a");

You can always skip a challenge by clicking on the next circle in the "stage bar" over the video area. You can also go to the course index page and pick any video from any stage there.

But the problem in your answer is that you created a variable named "container1", but then you reference an undefined one named "container" (without the "1").

And your answers are otherwise OK, but you could make them a bit less specific. For example, a more literal translation of "links in the nav element" into a selector would be just "nav a".

let navigationLinks = document.querySelectorAll("nav ul li a")

for the first row and the second and third row will work the same way. You need 3 rows only and you can use querySelectorAll for all of them.
