Use cases
-
Use text-spacing-trim
Use text-spacing-trim when the default CSS behavior is not expressive enough for the component or layout you are building.
-
Handle edge cases
Apply text-spacing-trim to solve a specific styling constraint without introducing broader layout or behavior changes.
Cautions
- Test text-spacing-trim in the browsers you support, especially if it changes layout, text handling, or interaction behavior.
- Plan a fallback or acceptable degradation path when support is still limited.
Accessibility
- Confirm that using text-spacing-trim does not make content harder to perceive, understand, or operate in assistive contexts.
