CSS Transform does not affect document flow. The DOM element will occupy it's original position and dimensions within the page flow.

So if you have 3 square div's of identical size, displayed inline in a row and apply a -webkit-transform: scale(2) to the center square, this square will scale up to 200% larger, scale from the center of its original position, and overlap both other squares.

Reference example:

HTML:

CSS:

.square{
  margin-top:50px;
  width:50px;
  height:50px;
  display:inline-block;
}

.one{
  background:#222;
}

.two{
  background:#888;
  -webkit-transform: scale(2);
}

.three{
  background:#ccc;
}
