-moz-transform Redirect 1

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use 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 spec changes.


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 according to the values set.

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

One or more of the CSS transform functions to be applied, see below.
Specifies that no transform should be applied.

Live Example

pre {
     width: 33em;
     border: solid red;

    -webkit-transform: translate(100px) rotate(20deg);
    -webkit-transform-origin: 60% 100%;

    -o-transform:translate(100px) rotate(20deg); 
    -o-transform-origin:60% 100%;

    transform: translate(100px) rotate(20deg);
    transform-origin: 60% 100%;

CSS transform functions

The transform CSS property allows the coordinate system used by an element to be manipulated using transform functions. These functions are described below.


transform:  matrix(a, c, b, d, tx, ty)

Specifies a 2D transformation matrix comprised of the specified six values. This is the equivalent to applying the transformation matrix (abtxcdty001) \begin{pmatrix} a & b & \mathrm{tx} \\ c & d & \mathrm{ty} \\ 0 & 0 & 1 \end{pmatrix} which maps coordinates from a new coordinate system into a previous coordinate system by the following matrix equalities: (xprevCoordSysyprevCoordSys1)=(abtxcdty001)(xnewCoordSysynewCoordSys1)=(axnewCoordSys+bynewCoordSys+txcxnewCoordSys+dynewCoordSys+ty1) \begin{pmatrix} x_{\mathrm{prevCoordSys}} \\ y_{\mathrm{prevCoordSys}} \\ 1 \end{pmatrix} = \begin{pmatrix} a & b & \mathrm{tx} \\ c & d & \mathrm{ty} \\ 0 & 0 & 1 \end{pmatrix} \begin{pmatrix} x_{\mathrm{newCoordSys}} \\ y_{\mathrm{newCoordSys}} \\ 1 \end{pmatrix} = \begin{pmatrix} a x_{\mathrm{newCoordSys}} + b y_{\mathrm{newCoordSys}} + \mathrm{tx} \\ c x_{\mathrm{newCoordSys}} + d y_{\mathrm{newCoordSys}} + \mathrm{ty} \\ 1 \end{pmatrix}

Note: Older versions of Gecko (Firefox) accepted a <length> value for tx and ty. Current Gecko, along with Webkit (Safari, Chrome) and Opera, supports a unitless <number> for tx and ty.

Live examples

 background: gold;  width: 30em;

 -webkit-transform: matrix(1, -0.2, 0, 1, 0, 0);
      -o-transform: matrix(1, -0.2, 0, 1, 0, 0);
         transform: matrix(1, -0.2, 0, 1, 0, 0);

 background: wheat;
 max-width: intrinsic;

 -webkit-transform: matrix(1, 0, 0.6, 1,  250, 0);
      -o-transform: matrix(1, 0, 0.6, 1,  250, 0);
         transform: matrix(1, 0, 0.6, 1,  250, 0);

Further knowledge


transform:  rotate(angle);       /* an <angle>, e.g., rotate(30deg) */

Rotates the element clockwise around its origin (as specified by the transform-origin property) by the specified angle. The operation corresponds to the matrix [cos(angle) sin(angle) -sin(angle) cos(angle) 0 0].


transform:  scale(sx[, sy]);     /* one or two unitless <number>s, e.g., scale(2.1,4) */

Specifies a 2D scaling operation described by [sx, sy]. If sy isn't specified, it is assumed to be equal to sx.


transform:  scaleX(sx);          /* a unitless <number>, e.g., scaleX(2.7) */

Specifies a scale operation using the vector [sx, 1].


transform:  scaleY(sy)           /* a unitless <number>, e.g., scaleY(0.3) */

Specifies a scale operation using the vector [1, sy].


transform:  skew(ax[, ay])       /* one or two <angle>s, e.g., skew(30deg,-10deg) */

Skews the element along the X and Y axes by the specified angles. If ay isn't provided, no skew is performed on the Y axis.

Note: The skew() function was present in early drafts. It has been removed but is still present in some implementations. Do not use it.

To achieve the same effect, use skewX() if you were using skew() with one parameter or matrix(1, tan(ay), tan(ax), 1, 0, 0) for the general way. Note that tan() isn't a CSS function and you have to precalculate it yourself.


transform:  skewX(angle)         /* an <angle>, e.g., skewX(-30deg) */

Skews the element along the X axis by the given angle.


transform:  skewY(angle)         /* an <angle>, e.g., skewY(4deg) */

Skews the element along the Y axis by the given angle.


transform:  translate(tx[, ty])  /* one or two <translation-value> values */

Specifies a 2D translation by the vector [tx, ty]. If ty isn't specified, its value is assumed to be zero.

Each <translation-value> arguments may be either a <length> value or a <percentage> value.


transform:  translateX(tx)       /* <translation-value> */

Translates the element by the given amount along the X axis.


transform:  translateY(ty)       /* <translation-value> */

Translates the element by the given amount along the Y axis.

Internet Explorer 5.5 or later supports a proprietary Matrix Filter which can be used to achieve a similar effect.

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.

Android 2.3 has a bug where input forms will "jump" when typing, if any container div has a -webkit-transform.
