How to animate the css zoom property

Question

Is it possible to get a smooth transition for the css zoom property?

I googled a lot, but the results for the keywords "css" and "zoom" are always about transform and transition. So, I don't want to know how to do it with transform and scale and so on. Just with the css zoom property.

document.querySelector('div').addEventListener('click', function(e) {
  e.target.classList.toggle('zoom');
});

div {
  width: 50px;
  height: 50px;
  background: red;
  cursor: pointer;
}

.zoom {
  zoom: 200%;
}

<div>click me!</div>

Answer 1

Non-standard This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The non-standard zoom CSS property can be used to control the magnification level of an element. transform: scale() should be used instead of this property, if possible. However, unlike CSS Transforms, zoom affects the layout size of the element.

MDN

So, you can use scale for this.

document.querySelector('div').addEventListener('click', function(e) {
  e.target.classList.toggle('zoom');
});

div {
  width: 50px;
  height: 50px;
  background: red;
  cursor: pointer;
  transition:.5s;
  transform-origin:left top;
}

.zoom {
  transform:scale(2);
}

<div>click me!</div>
