CSS Cascade
- Resolved: Cascade proximity is weaker than specificity (Issue #6790: Strong vs weak scoping proximity)
- Resolved: The combinator is deferred (Issue #8628: Do we want to defer some or all of these scope extensions to level 7?)
- Resolved: The name will be @scope-siblings (Issue #7751: Handle sibling-proximity in @scope)
CSS Animations
- Resolved: Include `overlay` property with values of `auto` and `none` to position-4 with a note about concerns over extensibility (Issue #8189: Entry and exit animations for top-layer elements)
CSS Contain
- Resolved: Elements within a display:none subtree have no parents that container queries can access (Issue #8197: Container queries within display:none are difficult to implement)
- Resolved: Add a function for every container query unit that allows to reference a named container (Issue #7858: Reference named containers for cq units)
- Resolved: Style queries can accept properties in boolean context; false if matches initial value, true otherwise (Issue #8127: Allow container query style features to evaluate in a boolean?)
- It’s unclear if the questions in issue #7875 (`overflow: auto` incompatible with size containment and container queries) are covered in the spec and need clarification or if there are changes to be made to handle contain-intrinsic-size.
CSS Color
- Resolved: Allow out-of-gamut HSL and HWB colors (Issue #8444: Allow out-of-gamut HSL/HWB colors (previously “Move gamut mapping to a future spec”))
- Resolved: Change specification say browsers MUST use OKLab color interpolation for all colors, including legacy colors (Issue #7948: What if legacy colors *also* interpolated in Oklab by default?)
