In brief
The beginning and the end do not always coincide with the left and right.
Useful to know
margin-inline sets the outer spacings along the line axis. In usual horizontal writing, they are left and right, but compliance depends on writing-mode and direction. [1]
Example: .article { max-width: 70ch; margin-inline: auto; }. In a standard block layout, it is a convenient way to horizontally center a bounded-width text. Two values set the spacing at the beginning and end of the line axis. In the case of components for different scripts, logical properties reduce the need for separate rules for physical sides.
