transform CSS property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2015.
The transform CSS property lets you rotate, scale, skew, or translate an element.
It modifies the coordinate space of the CSS visual formatting model.
If the property has a value different from none, a stacking context will be created.
In that case, the element will act as a containing block for any position: fixed; or position: absolute; elements that it contains.
You can also use the individual transform properties: translate, rotate, and scale. These properties are applied in the order: translate, rotate, scale, and finally transform.
Warning:
Only transformable elements can be transformed.
That is, all elements whose layout is governed by the CSS box model except for: non-replaced inline boxes, table-column boxes, and table-column-group boxes.
Try it
transform: matrix(1, 2, 3, 4, 5, 6);
transform: translate(120px, 50%);
transform: scale(2, 0.5);
transform: rotate(0.5turn);
transform: skew(30deg, 20deg);
transform: scale(0.5) translate(-100%, -100%);

Syntax
/* Keyword values */
transform: none;
/* Function values */
transform: matrix(1, 2, 3, 4, 5, 6);
transform: matrix3d(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1);
transform: perspective(17px);
transform: rotate(0.5turn);
transform: rotate3d(1, 2, 3, 10deg);
transform: rotateX(10deg);
transform: rotateY(10deg);
transform: rotateZ(10deg);
transform: translate(12px, 50%);
transform: translate3d(12px, 50%, 3em);
transform: translateX(2em);
transform: translateY(3in);
transform: translateZ(2px);
transform: scale(2, 0.5);
transform: scale3d(2.5, 1.2, 0.3);
transform: scaleX(2);
transform: scaleY(0.5);
transform: scaleZ(0.3);
transform: skew(30deg, 20deg);
transform: skewX(30deg);
transform: skewY(1.07rad);
/* Multiple function values */
transform: translateX(10px) rotate(10deg) translateY(5px);
transform: perspective(500px) translate3d(10px, 0, 20px) rotateY(30deg);
/* Global values */
transform: inherit;
transform: initial;
transform: revert;
transform: revert-layer;
transform: unset;
The transform property may be specified as either the keyword value none or as one or more <transform-function> values.
Values
<transform-function>-
One or more of the CSS transform functions to be applied. The transform functions are combined from left to right – each function establishes a new coordinate space for the next function and so on – so the visual result matches the written order of the functions. Alternatively, keeping the parent coordinate space fixed, the same transformation can be described as applying the functions in reverse order (right to left).
none-
Specifies that no transform should be applied.
Accessibility
Scaling/zooming animations are problematic for accessibility, as they are a common trigger for certain types of migraine. If you need to include such animations on your website, you should provide a control to allow users to turn off animations, preferably site-wide.
Also, consider making use of the prefers-reduced-motion media feature — use it to write a media query that will turn off animations if the user has reduced animation specified in their system preferences.

Examples
>Translating and rotating an element
HTML
<div>Transformed element</div>
CSS
div {
border: solid red;
transform: translate(30px, 20px) rotate(20deg);
width: 140px;
height: 60px;
}
Result
Comparing the order of transform functions
The order of transform functions matters.
In this example, two boxes are rotated and translated by the same values, but the functions are in the opposite order. The dotted lines mark the X-axis before and after rotation.
HTML
<div class="original"></div>
<div class="one">1</div>
<div class="two">2</div>
CSS
.one {
transform: translateX(200px) rotate(135deg);
}
.two {
transform: rotate(135deg) translateX(200px);
}
Result
- Box 1 (first
translateX(), thenrotate()): The coordinate space first shifts200pxalong the X axis, then rotates135degwithin that shifted space, so the element ends up to the right of its original position, rotated. - Box 2 (first
rotate(), thentranslateX()): The coordinate space first rotates135deg, so the element then moves200pxalong the rotated axis, in the direction shown by the dotted lines. Please see Using CSS transforms and<transform-function>for more examples.
