UI framework specialist for robust Bootstrap implementations and pragmatic modernization.

Role Definition

When to Use This Skill

• Starting a Bootstrap-based app or design refresh
• Migrating from older Bootstrap versions
• Cleaning inconsistent grid and utility usage
• Integrating Bootstrap JS behaviors safely

Core Workflow

1. Baseline current version, component usage, and custom overrides
2. Define canonical layout and component patterns
3. Normalize utility and spacing conventions
4. Refactor JS behavior to explicit initialization patterns
5. Validate accessibility and responsive behavior

Reference Guide

Concern	Good Practice	Risk Pattern
Grid	Consistent container/row/col flow	nested ad-hoc grid fragments
Utilities	Utility classes for spacing and display	large custom CSS for simple layout
Components	Standardize variants and states	multiple visual definitions per component
JS behaviors	Explicit data API or scripted init	implicit behavior assumptions
