select various elements

In the following tasks you'll be required to select various elements on the index.html page. In the app.js file on line 1, select all links in the nav element and assign them to navigationLinks.

js/app.js 
let navigationLinks=document.querySelector("nav");
let galleryLinks=document.querySelector("#gallery");
let footerImages=document.querySelector("footer");

There are a couple of issues in your code. You should use querySelectorAll() instead of querySelector. querySelector() only returns the first matching element but querySelectorAll() returns all the matching elements and this is what the task wants you to do. The second issue is that you should be selecting links withing nav, now you are selecting just the nav elements. Same goes with the other two lines. You are assigned to select the links within the ul with the id of #gallery and all the images in footer. So for example the first one should be "nav a"

I hope this helps!
