CSS 的变换原点属性用于指定元素的旋转原点。它是元素旋转的点。它可以用于 2D 和三维旋转。

语法:

transform-origin: position | initial | inherit

属性值:

position: This specifies the position of the origin of rotation. It takes 3 values corresponding to the distance from the left edge of the box, the distance from the top edge of the box and the z-axis of rotation.

这些值可以用长度单位、百分比或关键字来指定。z 轴值始终使用长度单位指定。

示例 1: 以长度单位指定位置

```html <!DOCTYPE html>

             .outer {             margin: 50px;             border: 1px dotted;             position: relative;             height: 100px;             width: 400px;             background-color: lightgreen;         }

.box {             position: absolute;             border: 1px solid;             background: url( "https://contribute.geeksforgeeks.org/wp-content/uploads/geeksforgeeks-logo.png"             ) no-repeat;

background-size: cover;             height: 100px;             width: 400px;             transform: rotate(15deg);             transform-origin: 10px 30px;         }
