This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
SummaryEdit
The CSS transform
property lets you modify the coordinate space of the CSS visual formatting model. Using it, elements can be translated, rotated, scaled, and skewed.
If the property has a value different than none
, a stacking context will be created. In that case the object will act as a containing block for position
: fixed
elements that it contains.
Initial value | none |
---|---|
Applies to | transformable elements |
Inherited | no |
Percentages | refer to the size of bounding box |
Media | visual |
Computed value | as specified, but with relative lengths converted into absolute lengths |
Animatable | yes, as a transform |
Canonical order | the unique non-ambiguous order defined by the formal grammar |
Creates stacking context | yes |

Browser compatibilityEdit
[1] Gecko 14.0 removed the experimental support for skew()
, but it was reintroduced in Gecko 15.0 for compatibility reasons. As it is non-standard and will likely be removed in the future, do not use it.
[2] Before Firefox 16, the translation values of matrix()
and matrix3d()
could be <length>
, in addition to the standard <number>
.
[3] Internet Explorer 5.5 or later supports a proprietary Matrix Filter which can be used to achieve a similar effect.
Internet Explorer 9.0 or earlier has no support for 3D transforms. Mixing 3D and 2D transform functions, such as -ms-transform:rotate(10deg) translateZ(0);
, will prevent the entire property from being applied.
[4] Android 2.3 has a bug where input forms will "jump" when typing, if any container element has a -webkit-transform
.
[5] Internet Explorer 11.0 supports the -webkit prefixed variant as an alias for the default one.
