JavaScript JavaScript and the DOM Getting a Handle on the DOM Return Elements Using CSS Selectors

I can't select all the <a> tags like the question asks me to

I don't know what selector type to use or what to write in the brackets following. I've watched all the videos again and again and i'm pretty sure it doesn't say how to go down a path of elements to get to the end <a> tags inside the <nav> that its asking for. Im probably wrong but i can't get past this point at all. Any help would be greatly appreciated.

app.js
let navigationLinks = document.getElementsByTagName('nav ul li a');
let galleryLinks;
let footerImages;

Instead of getElementsByTagName, have you tried querySelectorAll?

Ahh thank you! I eventually searched the answer out online and found other people had hit this very problem on this stage because the content is not covered in the proceeding tutorials so far. So we are being asked to do something that hasn't yet been explained! šŸ˜‚šŸ˜‚ Thanks so much for your time in getting back to me. And yes, you were totally right! it was the querySelectorAll that i needed to use!! Thanks again!
