How to set the rotate rotation point by css3

2D rotation refers to rotating the element clockwise or counterclockwise in a two-dimensional plane. (the experience is better when used with transition)

Syntax format:

Transform:rotate (degrees)

Note:

Rotate is followed by degrees, and the unit is deg, for example, transform:rotate (180deg), which means rotation of 180 degrees.

When the angle is positive, it rotates clockwise; when it is negative, it rotates counterclockwise, such as transform:rotate (180deg) and transform:rotate (- 180deg).

The center point of the default rotation is rotated at the center point of the element.

Change the center point of the rotation:

Transform-origin

We can set where the element is rotated.

The transform-Origin attribute allows you to change the location of the transformation element.

A 2D transformation element can change the X and Y axes of an element. 3D converts the element, and you can also change the Z axis of the element.

Syntax format:

Transform-origin: x-axis y-axis z-axis

Note:

The following parameters x and y are separated by spaces, not commas

The center point of the xy default conversion is the center point of the element (50%)

You can also set pixels or orientation nouns to xy, such as top bottom left right center.

Examples are as follows:

123#div1 {position: relative; height: 200px; width: 200px; margin: 100px; padding:10px; border: 1px solid black;} # div2 {padding:50px; position: absolute; border: 1px solid black; background-color: red; transform: rotate (45deg); transform-origin:20% 40%;-ms-transform: rotate (45deg); / * IE 9 * /-ms-transform-origin:20% 40% / * IE 9 * /-webkit-transform: rotate (45deg); / * Safari and Chrome * /-webkit-transform-origin:20% 40%; / * Safari and Chrome * /} HELLO
