Chaining animations in transitions

Did you know that the transition CSS property has the ability to define the sequence of animations via comma:

transition: transform 3s ease-in-out 2s, opacity 4s ease-in 2.5s;

Here is a real-world example:

HTML:

<div id="hover-me">
  <div class="animate-me">
    <div class="rotate-animate-me"></div>
  </div>
</div>

CSS:

#hover-me{
  position: absolute;
  top:50%;
  left: 50%;
  width: 50px;
  height: 50px;
  transform: translate(-50%, -50%);
  background: #f00;
}
.animate-me{
  width: 100%;
  top: 0%;
  left: 0%;
  height: 100%;
  transform: scale(1);
  pointer-events: none;
}
.rotate-animate-me{
  width: 100%;
  top: 50%;
  left: 50%;
  height: 100%;
  pointer-events: none;
  background: #00f;
  position: absolute;
  
  transform: translate(-50%,-50%) rotate(0deg);
  transition: width 0.5s ease-in-out 0.1s, height 0.5s ease-in-out 0.1s;
}
#hover-me:hover .animate-me{
  position: absolute;
  top: -200%;
  left: -200%;
  margin-left: 200px;
  transform: scale(2);
  
  
  transition: left 1s ease-in-out, top 1s ease-in-out 1s, transform 1s ease-in-out 3s, margin-left 1s ease-in-out 4.5s;
}
#hover-me:hover .rotate-animate-me{
  background: #f0f;
  transform: translate(-50%,-50%) rotate(2700deg);
  width: 0;
  height: 0;
  transition: background 1s ease-in-out 2s, transform 2s ease-in-out 4s, width 1s ease-in-out 6s, height 1s ease-in-out 6s;
}

Here how it looks:
