Minutes Telecon 2025-09-24

• Resolved: Update WD of css-images-4 (Issue #12756: Updated WD of CSS Images 4)
• The group was given an overview of the proposal to address issue #12218 (How do min/max block sizes affect bottom margin collapse with last child?); first resolve intrinsic height, not including end margins of contents, then check the actual height, and if they’re the same we allow collapse. Concerns were raised about the implications of how the proposal would handle height:auto and calc-size(). Discussion will return to the issue and a few interested folks will discuss more offline.
• Resolved: When resolving align-content:normal on a table cell, we use safe alignment (Issue #12220: Does `vertical-align` on table cell set `align-content` safely or not?)
• Resolved: width:max-content prevents table-layout:fixed from working (Issue #10937: What sizing keywords allow fixed table mode?)
• In order to determine the best solution for issue #12732 (position-visibility: anchors-visible should be clear about when is visibility determined), the group will start by trying to understand what types of clipping should position-visibility be checking for. Once that is clear, the group can move on to answer some sub-questions.
• Resolved: ‘any’ keyword is allowed wherever ‘span-all’ is allowed, and omitted values that would default to ‘span-all’ default to ‘any’ for queries (Issue #12610: Add `any` keyword support to `anchored(fallback)` container queries)
• Resolved: No change for the default, we’ll investigate a switch (Issue #12682: fallback-position behavior: spec vs. expectation)
• Resolved: Syntax of animation-trigger is [`dashed-ident` `behavior/actions`]+# (Issue #12652: animation-trigger CSS syntax)
