Details

(Whiteboard: [anchorpositioning:m1])

Invalid if:

  • Used outside of inset property
  • Used in non-abspos positioning
  • Keyword used for anchor side does not match physical side e.g. left: anchor(top)
  • Anchor specified refers to itself e.g. anchor-name: --foo; anchor(--foo left). Possible since anchors can have anchors.

Need to give fallback in this case, or treat the entire property as invalid at compute time.
