Also calledinline-start, block-size, margin-inline
Properties named by writing direction — inline and block, start and end — rather than by physical edge. They make right-to-left support a property of the markup's `dir` attribute rather than a duplicate stylesheet, and the shorthands like `padding-inline` are shorter than the physical pairs they replace. The only real cost is that a team has to commit to them consistently, because a mix of physical and logical values is worse than either.
