The transform-style CSS property determines if the children of the element are positioned in the 3D-space or are flattened in the plane of the element.

If flattened, the children will not exist on their own in the 3D-space.

As this property is not inherited, it must be set for all non-leaf descendants of the element.

[1] In addition to the unprefixed support, Gecko 44.0 (Firefox 44.0 / Thunderbird 44.0 / SeaMonkey 2.41) added support for a -webkit prefixed version of the property for web compatibility reasons behind the preference layout.css.prefixes.webkit, defaulting to false. Since Gecko 49.0 (Firefox 49.0 / Thunderbird 49.0 / SeaMonkey 2.46) the preference defaults to true.
