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.

Summary

The transform-origin CSS property lets you modify the origin for transformations of an element. For example, the transform-origin of the rotate() function is the centre of rotation. (This property is applied by first translating the element by the negated value of the property, then applying the element's transform, then translating by the property value.)

Not explicitly set values are reset to their corresponding values.

  • Initial value 50% 50% 0
  • Applies to transformable elements
  • Inherited no
  • Percentages refer to the size of bounding box
  • Media visual
  • Computed value for <length> the absolute value, otherwise a percentage
  • Animatable yes, as a simple list of a length, percentage or calc(); when both values are lengths, they are interpolated as lengths; when both values are percentages, they are interpolated as percentages; otherwise, both values are converted into a calc() function that is the sum of a length and a percentage (each possibly zero), and these calc() functions have each half interpolated as real numbers.
  • Canonical order One or two values, with length made absolute and keywords translated to percentages

Syntax

Formal syntax: [ <percentage> | <length> | left | center | right | top | bottom] | [ [ <percentage> | <length> | left | center | right ] && [ <percentage> | <length> | top | center | bottom ] ] <length>?
transform-origin: x-offset                                   /* One-value syntax */   E.g.  transform-origin: 2px 
transform-origin: offset-keyword                                                      E.g.  transform-origin: bottom

transform-origin: x-offset y-offset                          /* Two-value syntax */   E.g.  transform-origin: 3cm 2px
transform-origin: y-offset x-offset-keyword                                           E.g.  transform-origin: 2px left
transform-origin: x-offset-keyword y-offset                                           E.g.  transform-origin: left 2px
transform-origin: x-offset-keyword y-offset-keyword                                   E.g.  transform-origin: right top
transform-origin: y-offset-keyword x-offset-keyword                                   E.g.  transform-origin: top right

transform-origin: x-offset y-offset z-offset                 /* Three-value syntax */ E.g.  transform-origin: 2px 30% 10px
transform-origin: y-offset x-offset-keyword z-offset                                  E.g.  transform-origin: 2px left 10px
transform-origin: x-offset-keyword y-offset z-offset                                  E.g.  transform-origin: left 5px -3px
transform-origin: x-offset-keyword y-offset-keyword z-offset                          E.g.  transform-origin: right bottom 2cm
transform-origin: y-offset-keyword x-offset-keyword z-offset                          E.g.  transform-origin: bottom right 2cm

Values

x-offset
Is a <length> or a <percentage> describing how far from the left edge of the box the origin of the transform is set.
offset-keyword
Is one of the left, right, top, bottom or center keyword describing the corresponding offset.
y-offset
Is a <length> or a <percentage> describing how far from the top edge of the box the origin of the transform is set.
x-offset-keyword
Is one of the left, right or center keyword describing how far from the left edge of the box the origin of the transform is set.
y-offset-keyword
Is one of the top, bottom or center keyword describing how far from the top edge of the box the origin of the transform is set.
z-offset
Is a <length> (and never a <percentage> which would made the statement invalid) describing how far from the user eye the z=0 origin is set.

The keywords are convenience shorthands and match the following <percentage> values:

keyword value
left 0%
center 50%
right 100%
top 0%
bottom 100%
