backface-visibility

The backface-visibility CSS property sets whether the back face of an element is visible when turned towards the user.

An element’s back face is a mirror image of its front face. Though invisible in 2D, the back face can become visible when a transformation causes the element to be rotated in 3D space. (This property has no effect on 2D transforms, which have no perspective.)

Values: This property is specified as one of the following keywords:

Values: visible The back face is visible when turned towards the user. hidden The back face is hidden, effectively making the element invisible when turned away from the user.

Syntax example: backface-visibility: visible;
