Minutes San Francisco F2F 2016-05-10 Part I: Scheduling, Round Display, CSS tables status update, CSS UI 4

Scheduling

• Microsoft has offered to host in January/February in Redmond, Washington.
• April/May will likely be in Tokyo or Kyoto area; people should look for any conflicts in this time period.

Round Display

• Florian presented his proposal for a MQ to tell if a device is rectangle, round, or unknown. Several people felt that unknown wasn’t necessary; if a device isn’t round it can be assumed to be rectangular.
• Resolved: remove device-radius MQ, add MQ for shape: rect | round with traditional boolean semantics
• There was a split in the group as to if viewport-fit should be defined now or if the group should wait for implementation experience with a middle ground proposed of giving some guidance, but keeping it loose until there’s implementations.
• Resolved:
  1. Accept viewport-fit with three values: cover, contain, auto.
  2. Initial value is auto. UA can do anything it wants as long as the content not designed for round screens is easily 100% viewable by the reader.
  3. Undefined what is outside the contained viewport for ‘contain’. UA can paint anything it wants, chrome, black, canvas background, @page background, photo of SF Bay Bridge, whatever.
• There were conflicting opinions on if polar origin was necessary and how it should interact with other properties (if it exists). The interested parties discussed it over lunch and come up with a solution to integrate the desired behavior with the motion-path spec, making the motion path spec stronger in the process. The proposal is:
  • combine polar-distance and motion-offset -> offset-distance
  • polar-angle -> offset path
  • polar-anchor and motion-origin -> offset anchor (initial value is auto) which copies the percentages from offset-origin so offset-position behaves like background position.
• Resolved: Accept current proposal as outlined by fantasai (above)
• The Motion Path spec will need to be renamed since it’s more about path positioning than it is about motion.
• Resolved: jihye added as an editor of Motion Path spec.

CSS tables status update

• gregwhitworth updated the group on his progress with the tables spec.
• It’s not ready for FPWD, but he’s looking for feedback from anyone interested in reviewing their work.

CSS 4 UI

• Florian will look through UA stylesheets to list explicitly what user-select:none applies to.
• Resolved: appearance:none for checkbox and radio become non-replaced elements.
• There was a proposed set of principles for ‘appearance’
  1. it shouldn’t change what you can do with it
  2. you can’t break web compat
  3. should not prevent improvements in the UI
  4. it might as well be useful so long as it doesn’t violate the other three principles.
• Resolved: add :playing and :paused pseudo-classes
