Before and after space

What happens to the before and after space of the block elements? Can you get rid of them? Or are they part of the box element as the margin property?

If you're talking about the space a pseudo-element might take ("div::before or div::after), this space is only allocated when you actually use the pseudo elements. Otherwise, no space is taken.

DOn't block level elements take some space before and after by default?

That would be the margins. Some elements (not all) have default margins but you can explicitly set them to 0.
