I created this product-preview card and I set the border-radius on the parent class, however, it is not showing at the top, I do not want this, is there a way to fix this, I suspect that the problem is with the image and that it is blocking the radius from showing in some way but I am not exactly sure.

Answer 1

Adding overflow: hidden; to the .parent container fixes that. Otherwise the "not-rounded" edges of the image overflow the container:
