Let’s add a simple animation. In it, the circle should move infinitely along the corners of the square.
Let’s do a little preparation before the animation.
One animation cycle of a div.circle element must take 8 seconds.
The animation should be repeated all the time.
Let’s add the animation name right away - circleMove.
We’ll use it to create a keyframe in the next step.
