Design System Rebuild: Accessibility-First Foundations

, ,

In Q1 2025, we rebuilt our entire design system from scratch. The driver? An accessibility audit revealed 47 critical issues.

The Problem

Our previous component library: - No semantic HTML patterns - Inconsistent ARIA attributes
- Failed color contrast (3.2:1 on buttons) - 23KB of JavaScript for basic interactions

Results

  • 100% WCAG 2.2 AA compliance
  • 8.7KB total (CSS only, 0 JS for 80% of components)
  • Zero violations in production for 3 months

Project: Q1 2025 ยท Team: 2 engineers, 1 designer
