Scroll-linked Animations

• Due to increased interest, the group revisited a demo that dino gave back in 2014 on how to handle scroll-linked animations.
• In the time since the demo, there has been in increase in usage of scroll-linked animations as well as the Houdini effort which may make it easier to support use cases.
  • As an example, exact pull-to-refresh behavior is likely out of scope, but it can be made easier.
• There were several different aspects that need to be addressed in order to spec this.
  • Should have triggers be pre-transform.
  • Anchor points need to be carefully defined in order to prevent undesirable behavior.
  • This may generally have performance issues but, like custom layout, authors will work out how to use it performantly.
  • Parallax triggered animations will need to be supported.
• The group went through a list of scrolling use cases shane had prepared (available here)
• Dino will take his original e-mail and turn it into an explainer document.

Fill & Stroke on CSS Text

• fantasai presented the work she and TabAtkins had done to draft how fill and stroke properties effect CSS Text. The work is currently in the text-decoration L4 spec. Major points include:
  • Redefining ‘fill’ and ‘stroke’ as shorthands of other properties
  • Incorporating background-like image capabilities
  • Handling inheritance / nesting via fill-origin and stroke-origin
  • Need to investigate more deeply into which “boxes” serve as sizing/positioning origins for text
  • SVG has text-decoration fills, which need to be handled as well
  • Multiple strokes were requested
• It was noted that stroke-align may be too difficult for this level
• In regards to dashing:
  • The dashing origin for text is not defined; therefore might not be appropriate for text to have dashed strokes.
  • Dashing on strokes may need to be synchronized with additional dashing capabilities for CSS borders.
• Resolved: Merge heycam’s spec paint spec with this proposal and put into FX repository
• Resolved: Add -webkit-background-clip-text to the spec stating that authors must not use it but browsers may support it. (Deprecated appendix.)
