3,419 PointsBubbling works from bottom of DOM tree upto the top, then how does selecting parent .listDIV apply to all list elements?
In Bubbling, acting on a child element, affects the parent. How does acting on parent Div element affecting all list items work out?

's affects the div
.
In the code, the parent listDiv is selected for attaching the event handlers. That way, when you act on one of the list items inside it (the "children"), that event will bubble up to the parent listDiv and trigger the event handler.
So because of "bubbling", the action occurs in the children, but the event is handled at the parent.
Does that make it clear?

So if any of the list items, the paragraph, or headline elements are clicked, the callback will trigger in this example. This has been mentioned in this video.
