Says there are only 3 link elements I see 4.

Getting an error code that says it is looking for 3 not 4 elements, but there are 4 elements that are tagged 'link.' I think they want me to not include the href link, but I don't know how to do that.

js/app.js 
let navigationLinks = document.getElementsByTagName('link')[0,2,3];
let galleryLinks;
let footerImages;

I think it means the links in the <nav> tag not the <head>.

But you also want to limit the selection to only those which are contained in the nav element. I can think of two ways you might do this.

You can combine two getElementsByTagName calls, or you could use a single querySelectorAll with a descendant selector to choose the right elements. Either way will work, but the latter might be a bit easier and more compact.
