Component Variants

Agent Workflow (MANDATORY)

Before implementation, use TeamCreate to spawn 3 agents:

1. fuse-ai-pilot:explore-codebase - Check existing variant patterns
2. fuse-ai-pilot:research-expert - cva/class-variance-authority docs

After: Run fuse-ai-pilot:sniper for validation.

Overview

Style	Characteristics	Use Case
Glass	Blur + transparency + glow	Premium, modern, hero
Outline	Border only, no fill	Secondary actions
Flat	Solid color, no effects	Dense UI, fallback

Quick Reference

CVA Card Variants

import { cva, type VariantProps } from "class-variance-authority";

const cardVariants = cva(
  "rounded-2xl p-6 transition-all duration-200",
  {
    variants: {
      variant: {
        glass: [
          "bg-white/80 backdrop-blur-xl",
          "border border-white/20",
          "shadow-xl shadow-black/5",
        ],
        outline: [
          "bg-transparent",
          "border-2 border-primary/30",
          "hover:border-primary/50",
        ],
        flat: [
          "bg-surface",
          "border border-border",
        ],
      },
    },
    defaultVariants: {
      variant: "glass",
    },
  }
);

Button Variants

const buttonVariants = cva(
  "inline-flex items-center justify-center font-medium transition-all",
  {
    variants: {
      variant: {
        glass: "bg-white/20 backdrop-blur-md border border-white/30",
        outline: "bg-transparent border-2 border-primary text-primary",
        flat: "bg-primary text-primary-foreground",
      },
    },
  }
);

Dark Mode Per Variant

const glassVariant = {
  light: "bg-white/80 backdrop-blur-xl border-white/20",
  dark: "bg-black/40 backdrop-blur-xl border-white/10",
};

// Tailwind
className="bg-white/80 dark:bg-black/40 backdrop-blur-xl"

Best Practices

DO

• Use CVA for type-safe variants
• Define all three styles consistently
• Handle dark mode per variant
• Add hover/focus states

DON'T

• Mix variant systems
• Forget default variant
• Skip dark mode
• Ignore hover states
