Minutes Telecon 2020-06-17
- Resolved: Accept change as proposed by fantasai [move top|bottom|center values from alignment-baseline to baseline-shift] unless strong impl argument (Issue #5180: Shift top | bottom | center values from alignment-baseline to baseline-shift)
- The group looked at several diagrams in order to understand the proposal to handle line-sizing and leading-trim (Issue #5168: Rethinking line-sizing and leading-trim). They were a drawing from dauwhe and a slideshow from fantasai. Slide 52 was recreated on a whiteboard and discussed in detail to reach a common understanding of the proposal.
- The proposal was well received and was an improvement over the existing behavior using line-height.
- There were some open questions which need to be answered prior to the spec being finalized:
- Determine if the spacing should use just the leading in the content’s line box or also have the assumed gap which includes the leading on adjacent line boxes.
- When looking at font metrics should this look at first available font or at the whole font family. First available gives more control to designers but the whole font family makes it less likely to get overlap when a fallback happens so might be a better default.
- Need to make clear that this doesn’t impact the line box model.
- Should this be two properties as proposed or one property that takes one or two values.
- Resolved: Adopt new model described in the issue, continue working on it (Issue #5168: Rethinking line-sizing and leading-trim)
- Resolved: Apply negative half leading to margin box edge (Issue #5178: line-height < 1 in a margin-box line layout model)
- Resolved: Define the central baseline so if the font has an explicit ideographic central baseline, use that. If not, use halfway between ideographic top and bottom. If that’s missing, halfway between ascent and descent (Issue #5177: About the central baseline)
- The text for issue #1254 (‘line-height: normal’ definition should reflect reality of determining based on fonts) needs to be reviewed but will stay in the spec as-is for now.
- Resolved: Publish updated working draft of CSS-Inline
