What to use when positioning elements: margin or position relative?

Question

css

Let's say there is a block that comes after the header menu. It is necessary to make sure that there is a heading in the center of the block, some text under it and then a button.

What property should be used so that the title, subtitle and button are placed exactly as they are on the layout - position:relative with top/left or margin (top + left) specified?
