JavaScript JavaScript and the DOM (Retiring) Getting a Handle on the DOM Practice Selecting Elements

I don't know how to solve the third challenge task.

Finally, select all images inside the footer element and assign them to the variable footerImages.

Bummer: Are you selecting all images inside the '<footer>' element and assigning them to the variable 'footerImages'?

Also, for the second challenge task, why was '#' added to gallery?

Thank you and I appreciate the assistance I have been receiving when I ask questions.

js/app.js
let navigationLinks= document.querySelectorAll('nav a');
let galleryLinks=document.querySelectorAll('#gallery a');
let footerImages=document.querySelectorAll('#footer a').inputValue;

To answer the second question when you use the querySelector or the querySelectorAll methods to select elements you pass in strings as selectors in the same way that you would use selectors in CSS, to style elements. So using the # would indicate that you want to find a specific element with a particular ID.

To that end, for your third selecton attempt in JavaScript the first thing I would try is passing in "footer img" as the string or "footer a img". This would ensure you're selecting the elements the challenge wants which are images inside the footer element. And don't worry about looking for the value on the last one. :)
