Tailwind Advanced Patterns

# Tailwind Advanced Patterns for Google Antigravity

Create beautiful, reusable UI components with Tailwind CSS using Google Antigravity IDE.

## Button Component with Variants

```typescript
// components/ui/button.tsx
import { forwardRef } from "react";
import { Slot } from "@radix-ui/react-slot";
import { cva, type VariantProps } from "class-variance-authority";
import { cn } from "@/lib/utils";

const buttonVariants = cva(
  "inline-flex items-center justify-center rounded-md text-sm font-medium transition-colors focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring disabled:pointer-events-none disabled:opacity-50",
  {
    variants: {
      variant: {
        default: "bg-primary text-primary-foreground hover:bg-primary/90",
        destructive: "bg-destructive text-destructive-foreground hover:bg-destructive/90",
        outline: "border border-input bg-background hover:bg-accent",
        secondary: "bg-secondary text-secondary-foreground hover:bg-secondary/80",
        ghost: "hover:bg-accent hover:text-accent-foreground",
        link: "text-primary underline-offset-4 hover:underline"
      },
      size: {
        default: "h-10 px-4 py-2",
        sm: "h-9 rounded-md px-3",
        lg: "h-11 rounded-md px-8",
        icon: "h-10 w-10"
      }
    },
    defaultVariants: {
      variant: "default",
      size: "default"
    }
  }
);

export interface ButtonProps
  extends React.ButtonHTMLAttributes<HTMLButtonElement>,
    VariantProps<typeof buttonVariants> {
  asChild?: boolean;
}

const Button = forwardRef<HTMLButtonElement, ButtonProps>(
  ({ className, variant, size, asChild = false, ...props }, ref) => {
    const Comp = asChild ? Slot : "button";
    return (
      <Comp
        className={cn(buttonVariants({ variant, size, className }))}
        ref={ref}
        {...props}
      />
    );
  }
);
Button.displayName = "Button";

export { Button, buttonVariants };
```

## Card Component

```typescript
// components/ui/card.tsx
import { forwardRef } from "react";
import { cn } from "@/lib/utils";

const Card = forwardRef<HTMLDivElement, React.HTMLAttributes<HTMLDivElement>>(
  ({ className, ...props }, ref) => (
    <div
      ref={ref}
      className={cn("rounded-lg border bg-card text-card-foreground shadow-sm", className)}
      {...props}
    />
  )
);
Card.displayName = "Card";

const CardHeader = forwardRef<HTMLDivElement, React.HTMLAttributes<HTMLDivElement>>(
  ({ className, ...props }, ref) => (
    <div ref={ref} className={cn("flex flex-col space-y-1.5 p-6", className)} {...props} />
  )
);
CardHeader.displayName = "CardHeader";

const CardTitle = forwardRef<HTMLParagraphElement, React.HTMLAttributes<HTMLHeadingElement>>(
  ({ className, ...props }, ref) => (
    <h3 ref={ref} className={cn("text-2xl font-semibold leading-none tracking-tight", className)} {...props} />
  )
);
CardTitle.displayName = "CardTitle";

const CardContent = forwardRef<HTMLDivElement, React.HTMLAttributes<HTMLDivElement>>(
  ({ className, ...props }, ref) => (
    <div ref={ref} className={cn("p-6 pt-0", className)} {...props} />
  )
);
CardContent.displayName = "CardContent";

export { Card, CardHeader, CardTitle, CardContent };
```

## Best Practices

1. **Use CVA** for variant-based styling
2. **Create compound components** for flexibility
3. **Forward refs** for accessibility
4. **Use cn() helper** for class merging
5. **Define design tokens** in tailwind.config
6. **Build responsive by default**
7. **Follow accessibility guidelines**

Google Antigravity helps generate Tailwind components with proper accessibility.
