Use cases
-
Legacy retina support
Keep older high-density targeting rules alive while migrating to standard queries.
-
Compatibility cleanup
Document and isolate older prefixed rules until support requirements let you remove them.
Cautions
- Prefixed compatibility code should be temporary and intentionally bounded.
- Too many duplicate media-query branches make maintenance harder than the benefit they provide.
Accessibility
- Compatibility work should still preserve readable assets and robust zoom behavior.
- Do not let prefixed branches drift into inaccessible or untested variants.
