- Resolved: Change the text for
overflow:hidden not scrolling from SHOULD to MUST.
- Resolved: For the quoted Overflow spec text we are changing SHOULD to MUST and MAY to MUST.
- Resolved: No change on this issue (more detailed hyphenation policy).
- Resolved: No change to the spec because it already requires customary line breaking rules (in reference to this issue).
- Resolved: Use
place-items place-self place-content shorthands.
- The group will revisit the use of slashes once people have had more time to review and think through the implications.

CSS Scroll Snap Candidate Rec Published
The CSS Working Group has published a Candidate Recommendation of CSS Scroll Snap. This module contains features to control panning and scrolling behavior with “snap positions”, to which the UA is biased to land after a scroll operation.
We expect some minor adjustments to be made to the module as we gather
implementation experience in the CR cycle, however the module should be
mostly stable now. Significant changes since the last Working Draft are listed in the Changes section and include renaming ‘scroll-snap-padding’ to ‘scroll-padding’ and expanding
its application to exclude the scroll padding area in other forms of scroll
position calculations, such as scrolling to a :target or using PageUp/Down
operations. (See https://www.w3.org/TR/css-scroll-snap-1/#scroll-padding for details.)
Please send feedback by filing an issue in GitHub (preferable) with the spec code ([css-scroll-snap]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
CSS Grid Candidate Rec Published
The CSS Working Group has published a Candidate Recommendation of CSS Grid. Grid defines a new type of layout manager, the grid, which makes it extremely easy to specify complex, responsive 2-dimensional layouts for a page or sub-component of the page.
This spec is the culmination of years of design. In 2005, Bert Bos published the first draft of Advanced Layout, containing the proto-forms of what would eventually become Grid and Flexbox (along with tabbed layout, which never became a thing). While this received occasional updates, the Grid part didn’t receive much implementor interest until 2011, when editors from Microsoft published the first draft of Grid Layout. This attracted the attention of fantasai and Tab, who’d always liked the very similar Template Layout proposal from Bert’s draft, and they gradually merged the two proposals into the Grid spec now being published. Yay for collaboration!
We expect some minor adjustments to be made to the module as we gather
implementation experience in the CR cycle, however the module should be
mostly stable now. Changes since the last Working Draft are listed in the Changes section.

- Resolved: Rich text copy/paste is undefined in Text Level 3.
- Originally the group resolved that plain text copied to the clipboard must (or should) not be affected by text-transform in Text Level 3, but there was an objection from koji so the group will revisit next week.
- dbaron requested more time to look at absolutely positioned boxes in inline relatives being interoperable, so discussion will continue on github
- Resolved: 0px width float that is next to a line box does count as shortening a line box
- Resolved: Change “
baseline|last-baseline” to “[ first | last ]? baseline“
- Resolved: Match webkit/blink behavior for initial value of
mask-repeat and mask-position
- Resolved: ChrisL, TabAtkins, and shane as editors for Masking spec.
- Resolved: Add hoisting of listed properties other than overflow.

- Most of the call was dedicated to discussing how to and if we should define the effect of text-transform on copy/paste (CSS Text Issue #108)
- As a general principle there was a desire to have copy/paste match what users are seeing when they copy, however several people believed that the actual use cases in this case overrode the principle.
- There were four main use cases that the group uncovered:
- Turning a heading into all caps
- Turning a first line into all caps
- Turning acronyms into small case when they’re all caps in the source
- A ruby use case around ruby where in Japanese “しゃ” reads “sha”, and “しや” reads “shiya”. If that’s your ruby, there can be a text-transform to turn one into the other, because at small sizes it is hard to tell apart and smaller letters are hard to read. But out of context, you don’t want to change the pronunciation.
- Though mostly in the above use cases preserving the text-transform would be the worse user experience, there are times where you would expect preservation
- Consistency between inner text, paste to plain text, and range to string was another thing to be considered in the decision.
- In a straw poll the group was about evenly split between copied plain text ignoring text-transform or leaving it up to UA for UX decision.
- Group members will look through browser bugs to try and determine user expectations.
- There was also a desire to conduct a through user survey, though no one was tasked with creating one.
- Resolved: White space property is applied to plain text paste output.
- Resolved: Don’t define interaction between hanging punctuation and kerning and leave it up to UA to decide how to adjust.
- fantasai will write up her proposal to address hanging-punctuation scrollable overflow for review as there wasn’t time on the call.

- There is a move to finalize the April/Japan dates so anyone with conflicts should put them on the list.
- Resolved: Keep our should/must/may testing in place and put it into the web documentation.
- Resolved: We start the list of steps given at here keeping the test harness in working order as each step is done. We let gsnedders and those doing the work decide when to move steps.
- Resolved: Remove CSS grammar section in CSS 2.2 and have a pointer to CSS syntax.
- fantasai will write up proposed spec text for a definition of line-height calculations which will describe Blink and Gecko do.
- The minimum and preferred width of a multicol definition is in Syntax spec.
- Positioning boxes with
float:left; width:0px; will wait until next week to give people time to review the github comments.

- TabAtkins summarized his proposal for creating overflow-gap: auto | stable | always. Rossen asked if making these optional values for auto on the overflow property would make more sense as it would avoid creating another property. This was considered and a few people originally expressed no preference, but the more it was discussed the more people felt this was the wrong approach. There still wasn’t agreement as to if this new property should be a longhand of the overflow: auto or if it should be completely separate.
- Resolved: We will work on a solution to accommodate issue 92
- Resolved: The normal value of align-self and justify-self preserves aspect of image but stretch causes it to stretch to fit containing block. Default value continues to be normal.
- Resolved: Accept the proposal for Text issue 96 (for linebreak transformation rules ambiguous characters are narrow unless it’s Chinese or Japanese or Yi in which case they are wide)
- Resolved: Make tab size animatable
- Resolved: Make tab size a number
- Resolved: Have tab-size account for letter spacing and word spacing
- Resolved: No change to the spec for Text issue 110
- Resolved: Capitalize only title cases lower case things, not upper case letters
- Resolved: text-align-last: justify will compute to center for CJK

- Resolved: Don’t have the computed value dependency.
- The conversation around url parsing contradiction between 2.1 and Syntax needed TabAtkins, dbaron, and Bert and none of them were available today so it was postponed.
- There was a strong leaning toward using the metrics of the first available font for line height calculations. Rossen wanted to confirm there was minimal compat implications so he asked that the formal resolution wait until TPAC.
- Resolved: Don’t disallow 0 width tab size.

- There wasn’t interest at this time in creating a new pseudo-element which would apply offset-path to specify the shape of progress element. Exploration should focus around custom elements and any problems in the implementation of SVG that is causing it not to be performant.
- The scroll-snap-padding vs snap-padding topic will be added to the TPAC agenda.
- Resolved: Keep the name grid-gap (Grid issue #19).
- astearns filed an issue to add an example documenting the difference between the space in grid-gap and a traditional gutter.
- Resolved: Have percentages in grid-gap behave as percentages in tracks (Grid issue #20).
- Resolved: Keep auto-flow in the grid shorthand (Grid issue #24).
- Mats wasn’t on the call, so the discussion to reconsider the block-axis baseline decision will continue on the mailing list or github.
- Resolved: Have grid and flexbox keep saying that empty boxes have no baseline and they’re synthesized with bottom border edge.
- There was general agreement to accept the proposal that layout containment should make an element containing block for absolute/fixed positioned elements, but TabAtkins needed to check with the implementor first.

- A reminder that the registration for TPAC closes and registration fees go up soon.
- gregwhitworth will likely be the one to speak at the dev meet-up and he’ll cover topics around Grid.
- The behavior of what we do when there isn’t a natural baseline is inconsistent both between specs and between implementations.
- The proposals of what to standardize around were:
- Make boxes without a natural baseline and boxes establishing an orthogonal flow synthesize a baseline.
- Base this synthesized baseline on the margin box edges
- Base this synthesized baseline on some other box edge
- Make boxes without a natural baseline and boxes establishing an orthogonal flow use start alignment instead of trying to synthesize a baseline.
- Something else.
- Resolved: Accept option A2 with the modification that we’re talking about the border box.
- Several people had reservations on adding a new syntax (+#) to make it easier to read a legacy behavior that could still be written as [ + ]#
- Resolved: Don’t add any new syntax, just add a note explaining it.
- Resolved: Adopt the Gecko/Edge behavior and specify that
.offsetParent is based on the nearest abspos containing block or table cell
- Resolved: Accept the proposal (Proposal: Make the device-width/etc MQs use the same concepts as CSSOM is using for returning device dimensions.)
- The group began discussing adding device-pixel-ratio but didn’t have time to reach a decision
- One opinion was that it shouldn’t be added in order to encourage people to use ‘resolution’
- The other opinion was because ‘-webkit-device-pixel-ratio’ didn’t obviously translate to ‘resolution’, ‘device-pixel-ratio’ should be added to aid authors.
- Right as conversation was wrapping up, smfr asked a question about ‘window.devicePixelRatio’ which he was asked to post on github to allow further conversation.
