I tried a number of options, and did some editing of the HTML, but I'm somewhat stuck.

I think I'm making this harder than it needs to be. There has to be a simple solution. Thanks!

js/app.js 
let navigationLinks = document.querySelectorAll(".navigationLinks");
let galleryLinks;
let footerImages;

Hi there! Yes, there is a simple solution and yes, I think you're probably overthinking it. First, you are not meant to alter the HTML file at all. Secondly, you are meant to select the links. Remember links are anchor tags denoted by the <a> tag. Inside your querySelectorAll() you can use a "CSS selector". I see that you have some points in CSS so I'm guessing you will understand this example. If I wanted (in CSS) to select all h2 elements that reside inside a <div> tag, I could target those with this selector.

div h2 {
  /* Rules go here */
}

The div h2 is the selector. Thus, if I wanted to use a query selector to grab all h2 elements that reside inside a div, I could use querySelectorAll('div h2').

I think you can get it with these hints, but let me know if you're still stuck! :sparkles:
