It corresponds to the {{cssxref("margin-top")}}, {{cssxref("margin-right")}}, {{cssxref("margin-bottom")}}, or {{cssxref("margin-left")}} property depending on the values defined for {{cssxref("writing-mode")}}, {{cssxref("direction")}}, and {{cssxref("text-orientation")}}.
It relates to {{cssxref("margin-block-start")}}, {{cssxref("margin-inline-start")}}, and {{cssxref("margin-inline-end")}}, which define the other margins of the element.
The margin-block-end property takes the same values as the {{cssxref("margin-top")}} property.
