React Data GridLegacy Classic Style
Handsontable 16.1 introduced a new Classic (Modern) theme that replaces the legacy classic style. The legacy classic stylesheet will be removed in version 17.0.
About the Legacy style
The classic (legacy) CSS file (handsontable.full.min.css (opens new window)) was the default stylesheet up until version 15 (released in December 2024). This style is now considered legacy and will be removed in version 17.0.0.
Limitations of the Legacy Style
The legacy classic style was built with hardcoded styles that couldn't be customized with CSS variables. The new Classic (Modern) theme provides the same visual appearance but with the flexibility of CSS variables, making it easier to customize and maintain consistency with your application's design system.
Benefits of Migrating
- Visual Consistency: The new theme maintains the same visual appearance as the legacy theme
- Future-Proof: The new theme will continue to be supported and enhanced
- Console Warning: You'll see a deprecation warning if you're still using the legacy theme
