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.)

<p>
Since all faces are partially transparent,
the back faces (2, 4, 5) are visible
through the front faces (1, 3, 6).
