Supports descendant/child/adjacent/following-sibling relative paths, complex outer selectors, type/universal/class/ID, attribute presence and flag-bound equality/substrings, :is/:where/:not complex lists and root/first/last/only-child predicates. Relative paths can leave the anchor subtree via siblings. Has nesting and pseudo-elements within Has invalidate the selector; :is/:where discard syntactically invalid branches while :not/:has stay unforgiving. Only top-level selector entries containing Has are evaluated/count as relational; unrelated alternatives still participate in whole-list syntax validity but do not contribute matches. No An+B indexing, cascade/media applicability, computed/rendered state, dynamic pseudoclasses, namespaces, shadow matching, CSS nesting or external sheets are claimed; unsupported consumed profile is unknown. Quirks class/ID matching is unknown. Raw selector and relevant DOM attribute values are guarded; no source names/values are output." ], "module": "css-has-relative-selector-anchor-binding", "state": "not_observed", "value": { "adjacent_relation_steps": 0, "child_relation_steps": 0, "compiled_relational_selectors": 0, "descendant_relation_steps": 0, "embedded_stylesheets": 1, "following_relation_steps": 0, "forgiving_branches_discarded": 0, "has_function_sites": 0, "invalid_relational_rules": 0, "matched_selector_element_pairs": 0, "nonmatching_selector_element_pairs": 0, "relational_qualified_rules": 0, "relative_selector_branches": 0, "subjects_matching_any_relational_selector": 0 }, "warnings": [] } ], "known_count": 1, "scope": { "at": "2026-10-28T22:10:40.793Z", "contact_values_returned": false, "pages": 1, "rendered": false, "requests": 6 }, "warnings": [] }, "type": "json" }
