Use cases
-
Higher-contrast UI
Increase borders, text contrast, and focus visibility when the user has asked for stronger separation.
-
Preference-aware theming
Adjust visual density or contrast style without forcing a full theme switch.
Cautions
- The media query is a hint about preference, not a substitute for meeting baseline contrast requirements everywhere.
- Keep the default theme accessible even when the user has not set a system-level preference.
Accessibility
- This query directly supports users who need stronger contrast cues.
- Contrast adaptations should also preserve focus styles, borders, and distinguishable states.
