CSS - transform-style Property

Quiz

The CSS property transform-style determines whether an element's children are placed in a three-dimensional space or are flattened in the element's plane.

When flattened, the children of the element will not appear on their own in the three-dimensional space.

Since this property is not inherited, it should be set for all the non-leaf descendants of the specified element.

Possible values

The CSS property transform-style can have one of the following values:

flat: Specifies that the element's children are placed in the element's plane. It is the default value.
preserve-3d: Specifies that the element's children are placed in the three-dimensional space.

Applies to

All the transformable elements.

Syntax

transform-style = flat | preserve-3d
