如何使用javascript改变html中的元素顺序

I am creating a simple game that has 9 divisions and each 8 of the divisions have a penguin hidden in them and the 9th one has a monster. Now my game works fine but what I want to do is every time I load the page, arrangement of the divisions should change so as to add randomness to the game.I am creating a simple game that has 9 division
