The insertAfter() method inserts a new node immediately after a specified reference (child) node in the target node.
If the reference node is not found as a child of the target node, a DOMException exception will be thrown.
If the new node already exists in the DOM tree, it will be moved to the new position under the target node. This asserts that a node cannot be in two locations at the same time.
