3D Transforms Quiz question

I can't seem to get the proper answer for the question, "To tell the browser to hide the backside of a 3D element, we’ll need to use the __________ property and the ________ value ."

I've been trying multiple variations of what I know to be the correct answer. Frustrating... I reload the quiz and try again because I want to get all the questions right before I move on.

Any hint? (Even though I know the answer...)

I think what you're referring to is setting 'backface-visibility' to 'hidden'.

This can come in to play with optimizations and effects of 3D objects.

If you have an opaque object, backface culling can save the polys from being rendered. No point in drawing what won't be seen.

Transparent objects though might prefer not to have this enabled, since you'd want to see through the object to the back faces.
