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.
Summary
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 |
Animation type | a transform |
Canonical order | the unique non-ambiguous order defined by the formal grammar |
Creates stacking context | yes |

[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>
.
In addition to the unprefixed support, Gecko 44.0 (Firefox 44.0 / Thunderbird 44.0 / SeaMonkey 2.41) added support for a -webkit
prefixed version of the property for web compatibility reasons behind the preference layout.css.prefixes.webkit
, defaulting to false
. Since Gecko 49.0 (Firefox 49.0 / Thunderbird 49.0 / SeaMonkey 2.46) the preference defaults to true
.
[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.
Internet Explorer does not support the global values initial
and unset.
[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.
