How to make such contours for blocks?

Question

css

Tell me, please, how to make such borders for blocks?
For good, there should still be animation: when you hit this block, the border is drawn, so to speak. This is not yet necessary, but if you suddenly know the solution, I will be grateful!
Please help a specialist who has just resumed work after 3 years of maternity leave :)

I thought it would be very useful for you to read and figure it out yourself https://css-tricks.com/building-progress-ring-quickly/
This thing is called differently - radial progress, ring, progress, cyrcle progress, just google this name with with the addition of "css", you will find a lot of stuff.
