Direct CSS property control
Arbitrary properties let you express CSS declarations that do not have a dedicated Tailwind utility. This is useful for unusual CSS features or progressive enhancement.
CSS variables
Tailwind utilities can consume CSS variables, which makes it possible to combine application state with a utility-based design system.
Prefer tokens for repeated values
Arbitrary properties are best for isolated needs. Repeated values should become theme variables or normal CSS custom properties so the system remains consistent.
