Help with scrolling submenu, IntersectionObserver
I'm rewriting some old code we had that used window.onScroll to set the active state of the current sub-section of the page. I'm trying to use IntersectionObserver, but with short sections, it's observing two active sections at once. Essentially I'm looking to mimic the behavior of the side nav on Mozilla: https://developer.mozilla.org/en-US/docs/Web/API/Element/scroll_event - it only marks a section as active when it's on the top close to the sticky menu. Anybody have any good resources or code with examples?? Thanks!
The scroll event fires when an element has been scrolled.
To detect when scrolling has completed, see the Element: scrollend event.
