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

do i need to edit the html file?

i need to select al the links (listitems) within the "nav" tag. But the listitems don't have a combined id, class or name attribute assigned. and there are more dan those 3 <li> tags, so it is not possible to getElementsBySomeElement.

If i add a name attribute in the html file name="navli" to the listitems and set: let navigationLinks = document.getElementsByName("navli); or navigationLinks = document.querySelectorAll('[name=navli]');

it says: was expecting 3 items instead of 0.

let navigationLinks = document.getElementsByTagName('nav') ;
let galleryLinks;
let footerImages;

Hey remi poolen , you can use document.querySelectorAll to select all the links withing nav element.
Here is the code:

let navigationLinks = document.querySelectorAll('nav li a');

Similary for second question , you can type:

let navigationLinks = document.querySelectorAll('nav li a');
let galleryLinks =  document.querySelectorAll('#gallery li a');
let footerImages ;

And for the third question:

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

Hope it helps :)
