How do I make a div fly off the screen on click?

Okay so i've got this round div.

<div id = "dot"></div>

With this styling, it flies off the screen when you hover over it.

#dot {
  height: 75px;
  width: 75px;
  background-color: red;
  border-radius: 50%;
  margin: 0 auto;
  position: relative;
  top: 30vh;
  transition: all 2s;
}

#dot:hover {
  top: -1000vh;
}

#dot {
  -webkit-transition-timing-function: ease-in-out;
  transition-timing-function: ease-in-out;
}

I want the fly-off-the-screen transition to occur when the dot is clicked, and I'm looking for a solution that is pure CSS or vanilla javascript. If it's of any significance, the dot is ultimately gonna be wrapped in an a link element, and its dramatic exit will herald the load of a new page.

Bonus question: if this round div eventually has an SVG in it, will that negatively affect its performance/appearance?
