"Let us prepare our minds as if we'd come to the very end of life. Let us postpone nothing. Let us balance life's books each day ... The one who puts the finishing touches on their life each day is never short of time."
Seneca

margin-inline-end

The margin-inline-end CSS property defines the logical inline end margin of an element, which maps to a physical margin depending on the element's writing mode, directionality, and text orientation. In other words, it corresponds to the margin-top, margin-right, margin-bottom or margin-left property depending on the values defined for writing-mode, direction, and text-orientation.
