Let’s animate the flipping of the card
We’ll do some preparation at the first step.
Firstly, the back of the map (.face.back) must be rotated 180 degrees around the Y axis
Secondly, each side (.back and .front) must have a hidden back.
For the .card element, let’s immediately add a transition for the transition property with a duration of one second.
Well, don’t forget about the script to start the transition.
When clicking on the button on the front of the card - the .card element needs to be added the flipped class.
When you click on the button on the back of the card - the flipped class needs to be removed from the .card
