Selects all next elements matching "next" that are immediately preceded by a sibling "prev".
.next adjacent(prev, next)
prev
Selector Any valid selector.
next
Selector A selector to match the element that is next to the first selector.One important point to consider with both the next adjacent sibling selector (prev + next) and the general sibling selector (prev ~ siblings) is that the elements on either side of the combinator must share the same parent.
