Start one animation after the other is finished (infinitive)

Start one animation after the other is finished (infinitive)

Hi,

Looking at this Pen:


I like to achieve that the animation of the second element starts only after the animation of the first element is finished.
When the animation of the second element is finished, the animation of the third element should start and so on (infinitive).

Please feel free to change the code as you wish.

Thanks
