Developer use cases

  • Immediately I think of `grid` and `table` inner borders. - Add inner borders to tables that have `border-radius` (since they cannot have `border-collapse: collapsed`). - And grids that look like border-collapsed tables, such as a calendar's borders. - Gap color! - The potential for attractive plaid CSS.
