Zoom on image inside div without div moving

Question

How can I make the image inside of this div scale without the actual div scaling on hover? So I only want the image to get zoomed on.

Here is the code:

<div id="container">
    <img id="image" src="some-image">
</div>

Solution 1

Use transform: scale

#container {
  display: inline-block;
  margin: 20px;
  border: 1px solid black;
  overflow: hidden;            /* clip the excess when child gets bigger than parent */
}
#container img {
  display: block;
  transition: transform .4s;   /* smoother zoom */
}
#container:hover img {
  transform: scale(1.3);
  transform-origin: 50% 50%;
}

<div id="container">
    <img id="image" src="http://placehold.it/150">
</div>

Solution 2

a little bit elegant solution with transition effects

#container {
  display: inline-block;
  overflow: hidden;
}

#container img {
  display: block;
  -moz-transition: all 0.3s;
  -webkit-transition: all 0.3s;
  transition: all 0.3s;
}

#container:hover img {
  -moz-transform: scale(1.1);
  -webkit-transform: scale(1.1);
  transform: scale(1.1);
}

<div id="container">
    <img id="image" src="http://placehold.it/200">
</div>
