Originally implemented only in Internet Explorer. Note that transform: scale() does not work the same as zoom. If e.g. transform: scale(0.6) is used on the html or body element then it resizes the entire page, showing a minified page with huge white margins around it, whereas zoom: 0.6 scales the elements on the page, but not the page itself on which the elements are drawn.
