I am currently learning to code JS and like probably many other people before, I'm writing a ToDo List.

But at this point I've got a problem.

let DivNone = document.querySelectorAll('#div2, #btn3');


DivNone.style.display = 'none';

Why doesn't it work?

    That second example should work. Please add a [mre]. – 0stone0 Aug 25 '23 at 15:51

    `querySelectorAll()` does not return a single element; you will need to iterate over it to update each element's style. – mykaf Aug 25 '23 at 16:05
