Remarks

The version of this property using a vendor prefix, IHTMLCSSStyleDeclaration::transform, has been deprecated in Internet Explorer 10 and later. However, be aware that IHTMLCSSStyleDeclaration::transform 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: translate(200px, 100px) scale(.75, .75) rotate(40deg);
  -webkit-transform: translate(200px, 100px) scale(.75, .75) rotate(40deg);
  -moz-transform: translate(200px, 100px) scale(.75, .75) rotate(40deg);
  transform: translate(200px, 100px) scale(.75, .75) rotate(40deg);
}

For information about the transformation functions that are supported for use with the IHTMLCSSStyleDeclaration::transform property, see Transform Functions.

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

Examples

The following example is an ID selector that demonstrates the use of both the IHTMLCSSStyleDeclaration::transform and the IHTMLCSSStyleDeclaration::transformOrigin properties. In this case, the IHTMLCSSStyleDeclaration::transformOrigin property has been set to "60% 100%", which sets the transform's origin point to 60% of the length and 100% of the height of the element to be transformed. The IHTMLCSSStyleDeclaration::transform property first uses the translate function to move the element 50 pixels in the x direction and 10 pixels in the y direction. It then uses the scale function to scale the element by 75%. Finally, it uses the rotate function to rotate the element 45 degrees clockwise around the origin point set by the IHTMLCSSStyleDeclaration::transformOrigin property.

div {
   width: 100px;
   height: 100px;
   background-color: #D3D3D3;
   border: solid 2px; #000;
}
#mytransform {
  transform: translate(50px, 10px) scale(.75, .75) rotate(45deg);
  transform-origin: 60% 100%;
}

In image below, you can see the original element and the element after the IHTMLCSSStyleDeclaration::transform property has been used.
