Remarks

The version of this property using a vendor prefix, IHTMLCSSStyleDeclaration::transformOrigin, has been deprecated in Internet Explorer 10 and later. However, be aware that IHTMLCSSStyleDeclaration::transformOrigin is the only form of this property that is recognized by Windows Internet Explorer 9, which supports 2-D Cascading Style Sheets (CSS) transforms. To ensure maximum compatibility, specify a cascade such as the following, where the prefixed versions of the property come before the unprefixed version.

#mytransform {
  ...
  -ms-transform-origin: 60% 100%;
  -webkit-transform-origin: 60% 100%;
  -moz-transform-origin: 60% 100%;
  transform-origin: 60% 100%;
}

If the IHTMLCSSStyleDeclaration::transformOrigin property is not set, the transform begins in the center (equal to a IHTMLCSSStyleDeclaration::transformOrigin value of "50% 50%").

If only one value is specified, the second value is assumed to be center.

3-D transforms are only supported in Internet Explorer 10 and later.

As of Internet Explorer for Windows Phone 8.1 Update, Internet Explorer for Windows Phone supports "-webkit-transform-origin" as an alias for this property.
