We've defined 'margin-trim' to accept a list of sides to trim, with options for all four sides. For block containers (which previously only trimmed the block-start and block-end sides) there are a few interesting open questions:
- What effect, if any, should this have on inlines?
- What effect, if any, should this have on the inline-axis?
My proposed answer to this, btw, is that margin-trim applies to inlines in the inline axis, and to blocks in the block axis, and not to inlines in the block axis or to blocks in the inline axis. Reason being, these are the two things that seem useful.
Trimming blocks in the inline axis isn't very useful (they're always adjoining both sides, so just set your margins to zero) and trimming inlines in the block axis seems better served by leading-trim and other specialized text-sensitive things. Proposed definition means we can turn on the useful behaviors (inline-axis trimming of inlines, block-axis trimming of block) without simultaneously turning on unwanted behaviors (block-axis trimming of inlines, inline-axis trimming of blocks).
