transform-style

Determines if child elements should be rendered 'flat' against their parent or if they should exist in their own 3D space. This is essential for creating complex 3D scenes (like a rotating cube) where children need to overlap in a 3D environment.

It is documented as part of the CSS Transforms specification.

/* Usage Example */
.cube-container {
  /* Allows nested elements to stick out or hide behind each other in true 3D space */
  transform-style: preserve-3d;
  perspective: 1000px;
}

/* Syntax */
transform-style: flat;
transform-style: preserve-3d;

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