📋 Decision Context

Question:

What is the best pattern for modern, accessible tab navigation in our Vitto AI components?

Task: Standardize tab navigation styling across all Vitto AI components for consistent, modern UX

🎯 Decision Made

Chosen:

Modern tabs with floating active state and visual hierarchy

Options Considered:

1. Minimal flat tabs with underline
2. Card-style elevated tabs with gradients
3. Button-style tabs with borders
4. Modern tabs with floating active state

💭 Reasoning

After implementing various tab styles, we found that modern tabs with a floating active state provide the best UX. Key design decisions: (1) Larger clickable areas (48px min-height) for better accessibility, (2) Active tabs "float" above with transform, shadow, and top gradient indicator, (3) Strong color hierarchy: tertiary → secondary (hover) → primary (active), (4) Icon scaling on hover for micro-interactions, (5) Smooth transitions with proper easing, (6) Card-like active state with subtle elevation, (7) Semi-transparent hover states using color-mix(), (8) Consistent spacing using design tokens (--ux-spacing-*), (9) Font weight progression (500 → 600 → 700) for hierarchy. This pattern works universally for main navigation tabs and sub-tabs, providing clear visual feedback while maintaining a clean, professional aesthetic.
