jQuery()

Return a collection of matched elements either found in the DOM based on passed argument(s) or created by passing an HTML string.

.closest()

For each element in the set, get the first element that matches the selector by testing the element itself and traversing up through its ancestors in the DOM tree.

.next()

Get the immediately following sibling of each element in the set of matched elements. If a selector is provided, it retrieves the next sibling only if it matches that selector.
