Create Jumping Rings using css| Spring Action

Span is a tag that has no inbuilt properties but is powerful because it can work as any tag in HTML including the input tag. Here I created a jumping rings of circle using the span tag. I think here i used 14 span tags used to make 14 concentric circles. By making the box-sizing property to border-box makes the box size flexible (auto width and height).Note that the positionz need a 3d platform for proper jumping of the circles. So we create a property as follows

transform: perspective(500px) rotatex(60deg);

Here I also implemented the property rotatex to rotate the X-axis of the circle containing box.


LIVE PREVIEW:








See how the circles are jumping. To look the circle like jumping like a spring, I set a delay in time of the animations that I applied to the circle.

Here is the code of the jumping concentric circles.
