Targeting the nested div. Why can't you use document.QuerySelector?

// 5: Store the nested div in a variable named `banner`
const banner = list.previousElementSibling;
banner.className = 'banner';

I know we were supposed to use .previousElementSibling like above.

But why wouldn't this work?

const banner = document.querySelector('h1 div');

I also tried:

const banner = document.querySelectorAll('h1 div');

I thought this would target the first div under the first h1. Thank you!

The selector "h1 div" would target a div that is inside an h1 element. But nothing on the document fits that description.

The div in question is the adjacent sibling of the h1 element, and a selector for that would be "h1 + div".

Thank you Steven! That makes total sense.
