Key Findings
What Drove Adoption
- Zero-config theming — Teams could match brand guidelines by setting three custom properties instead of writing theme CSS from scratch.
- Accessibility built-in — Teams no longer needed to audit basic component accessibility; VB handles ARIA roles, focus management, and keyboard navigation.
- Reduced CSS maintenance — Average CSS bundle size dropped 40% across migrated projects.
Blockers
- Two teams reported issues with existing
!importantoverrides conflicting with VB’s cascade layers. - The mobile web team needed custom touch gestures not covered by existing components.
- Marketing requested animation capabilities beyond VB’s current text effects.
Detailed migration timeline per team
- Platform Engineering
- Migrated October 2025. Full adoption in 3 weeks. No blockers.
- Product — Dashboard
- Migrated November 2025. Incremental adoption over 6 weeks. Minor cascade conflicts resolved.
- Internal Tools
- Migrated September 2025. Fastest adoption. Pre-existing use of CSS custom properties made transition smooth.
Recommendations
- Set organization-wide target of 80% adoption by Q2 2026.
- Address mobile gesture gap with dedicated touch event component.
- Create migration playbook for teams with heavy
!importantusage. - Expand animation system to cover marketing use cases (parallax, scroll-driven).
