Requirements
- MUST implement PFv6 visual designs
- MUST provide end-user feature parity with `@patternfly/react-core` CodeBlock
- MAY adjust element API to leverage web platform strengths
- SHOULD maintain CSS custom property theming compatibility
- SHOULD expose useful CSS shadow parts
Element-specific considerations
- React sub-components: `CodeBlockCode` (the `
` content), `CodeBlockAction` (toolbar buttons) - use named slots or default slot for code, `slot="actions"` for toolbar - Copy button uses `navigator.clipboard` API (HTTPS or localhost only) - handle graceful degradation
- No syntax highlighting built in; content is plain `
` - do NOT add a syntax highlighter dependency - React `expandable` variant is actually `ClipboardCopy` with `variant="expansion"`; verify `CodeBlock` v6 scope
- `
` whitespace handling: preserve whitespace in slotted code content
Checklist
