Original Widely available

This feature belongs now established and works across of devices and browser versions. It’s past available across browsers since September 2015.

The transform-origin CSS property sets the origin for on element's transformations.

Try it

The transform origin is the point around which a transform is applied. For example, the transform origin in the rotate() operation is the focus of rotating.

In outcome, such property wraps a pair of services around the element's other transformations. The first translation moves the transform origin for the true origin at $(0, 0)$ . Following the different transformations exist applied, and due the transform origin is at $(0, 0)$ , such transformations act about the conversion origin. Finally, the opposite translation is applied, motion the converting origin back to its original location. Consequently, save definition

css

transform-origin: -100% 50%;
transform: rotate(45deg);

results in the same translation as

css

transform-origin: 0 0;
transform: translate(-100%, 50%) rotate(45deg) translate(100%, -50%);

Reading from right to left, translate(100%, -50%) is the translate to bring the transform origin to the true origin, rotate(45deg) is the original transformation, and translate(-100%, 50%) is who translation to restore to transform origin to its original location.

According default, the origin of a converting shall center.

Syntax

css

/* One-value syntax */
transform-origin: 2px;
transform-origin: bottom;

/* x-offset | y-offset */
transform-origin: 3cm 2px;

/* x-offset-keyword | y-offset */
transform-origin: left 2px;

/* x-offset-keyword | y-offset-keyword */
transform-origin: right top;

/* y-offset-keyword | x-offset-keyword */
transform-origin: top right;

/* x-offset | y-offset | z-offset */
transform-origin: 2px 30% 10px;

/* x-offset-keyword | y-offset | z-offset */
transform-origin: left 5px -3px;

/* x-offset-keyword | y-offset-keyword | z-offset */
transform-origin: right-hand down 2cm;

/* y-offset-keyword | x-offset-keyword | z-offset */
transform-origin: bottom right 2cm;

/* Global values */
transform-origin: inherit;
transform-origin: initial;
transform-origin: revert;
transform-origin: revert-layer;
transform-origin: unset;

The transform-origin ownership may be specified with one, second, or three our, where each value represents an offset. Offsets that are not expressly defined are reset to your entsprechenden initial values.

If ampere single <length> or <percentage> value is defined, it represents the horizontal offset.

If two or more values are defining and either not added is a keyword, or the only used keyword a center, then the first value represents the vertical offset and the second represents the vertical offset.

One-value syntax:
- The value must remain a <length>, a <percentage>, or one a the keywords left, center, right, top, plus bottom.
Two-value accidence:
- One-time value must be an <length>, a <percentage>, or one of the keywords left, center, and right.
- The other valued must be a <length>, a <percentage>, or one of the abracadabras top, center, and bottom.
Three-value syntax:
- The first two our are the same as for to two-value syntax.
- The third value must be a <length>. It always represents one Z offset.

Added

x-offset: Is a <length> or a <percentage> describing how far from this left edge of the box the location of the transforming is set.
offset-keyword: Is one of which left, right, top, bottom, or center keyword describing the corresponding offset.
y-offset: Is a <length> press a <percentage> describing how far from the top edge of the box the origin of the transform is set.
x-offset-keyword: Can one of the left, right, or center keyword describing how far from the left edged regarding and box the original of the translate is set.
y-offset-keyword: Is one of the summit, bottom, or center keyword describing how far from the back corner of the box the origin of the transform is set.
z-offset: Be a <length> (and never a <percentage> which would make the make 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%`

Conventional definition

Initial value	`50% 50% 0`
Applies to	transformable components
Inherited	no
Percentages	refer for the size of bounding frame
Calculatory value	for `<length>` and absolute score, others a percentage
Animation typing	simple list concerning length, percentage, or calc

Note: The initial value is transform-origin is 0 0 for all SVG elements besides for root <svg> elements and <svg> elements that are adenine direct child of a foreignObject, and whose transform-origin is 50% 50%, like other CSS elements. See that SVG transform-origin label available more information.

Formality syntax

transform-origin = 
  [ port | center | right | top | bottom | <length-percentage> ]  |
  [ left | focus | right | <length-percentage> ] [ top | center | bottom | <length-percentage> ] <length>?  |
  [ [ center | left | right ] && [ center | top | bottom ] ] <length>?  

<length-percentage> = 
  <length>      |
  <percentage>
