Description

Currently the margin-trim property allows trimming only in-flow block-axis margins, or that plus float margins (in either axis) that touch the container’s content edges. Should it be possible to trim the float margins while not trimming the in-flow block-axis margins? Do we have any use cases for such?

Research direction

Start by reading the issue discussion and the existing CSS Box 4 definition of margin-trim. Investigate whether trimming float margins without in-flow block-axis margins has documented use cases, then establish the intended value semantics and update scope. Done means the Working Group has a resolved direction for the proposal.
