Use cases

  • Use glyph-orientation-vertical

    Use glyph-orientation-vertical when the default CSS behavior is not expressive enough for the component or layout you are building.

  • Handle edge cases

    Apply glyph-orientation-vertical to solve a specific styling constraint without introducing broader layout or behavior changes.

Cautions

  • Test glyph-orientation-vertical 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 glyph-orientation-vertical does not make content harder to perceive, understand, or operate in assistive contexts.
