HyphenationBaseline · Widely available

The hyphens CSS property controls when long words are broken by line wrapping. Although called hyphens, the property applies to word-splitting behavior across languages, such as customary spelling changes or the use of other characters. Support for non-English languages varies significantly.

Supported in all major browsers for at least 30 months — safe to use without fallbacks. Baseline since Sep 18, 2023. Widely available since Mar 18, 2026.
