How to add fixed balls?

Question

css

There is a layout, https://codepen.io/SergeyYmsk/pen/WNjQRWJ . On the strip, by design, white balls are placed, but if you add some text to the card, they will shift, the same trouble with the adaptive, although this is a slightly different issue. How can I add these circles so that they don't move?

Answer 1

The distance between the blocks and the line is the same, why would they move out?
