Hi Kim,

For this one you just need to change ".footer" to just "footer" as this is an element not a class, similar to the "nav" element selected on line 1.

Then you are selecting all anchor elements that are contained within an image, but this does not match the HTML. So you could just switch this round to "footer a img" or simply "footer img".

The best way to think about this is, if it will work in CSS to target it, then it will work in the query selector :)

let navigationLinks=document.querySelectorAll("nav ul li a");
let galleryLinks=document.querySelectorAll("#gallery li a");
let footerImages=document.querySelectorAll("footer img");

Hope this helps.
