Can I apply a CSS transition to the overflow property?

Question

I'm trying to set a transition-delay to the overflow property of body when a div is clicked by adding a class to the body as follows:

$("div").click(function(){
    $("body").addClass("no_overflow");
});

div{
  background:lime;
  height:2000px;
}
.no_overflow{  
 overflow:hidden;
}
body{  
  overflow:auto;
  transition: overflow 0 2s;  
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>I'm div</div>

There are many properties that can't be transitioned. overflow is among them; the render engine has no idea how to transition between "hidden" and "shown", because those are binary options, not intervals. This is the same reason why you can't transition between display: none; and display: block; (for example): there are no in-between phases to use as transitions.

You can see a list of properties you can animate here on Mozilla Developer Network.
