all
The all CSS property is a shorthand for all CSS properties, except for direction and unicode-bidi. It accepts only the keywords for explicit defaulting (such as initial and inherit), since they are the only values supported on all CSS properties.

Maintainable CSS architecture
Use all to make stylesheet intent clearer in larger codebases and shared design systems.
Fallback management
Control resets, imports, inheritance, or feature branches with explicit CSS rules instead of ad hoc duplication.
Cautions
- Cascade-level tools are powerful, so misuse can make style ownership harder to understand.
- Keep rules scoped and documented when they affect many selectors or entire stylesheets.
Accessibility
- Global CSS controls should not accidentally remove focus, contrast, or structural cues.
- Fallback paths should remain readable and functional, especially for assistive-technology users.
