Physical vs. logical properties

Physical properties

In right-to-left languages “One” should be positioned at the very right, but it's not because with physical properties every list item has its margin always on the right, no matter the reading direction.

Logical properties

Using logical properties, “One” is at the very right in right-to-left languages because logical properties don't work with the concept of top and bottom or left and right , but start and end , which may switch depending on the writing mode.
