# Landing Page Builder Skill

Build conversion-optimized landing pages for **Next.js (App Router) + shadcn/ui + Tailwind CSS + TypeScript** projects.

All output MUST be:
- React Server Components where possible (client only for interactivity)
- shadcn/ui components + Tailwind
- Mobile-first responsive
- Above-the-fold optimized (LCP < 2.5s)
- Accessible (ARIA, keyboard nav, contrast)

## 1. Hero Section Patterns

### Hero with CTA + Social Proof
```tsx
import { Button } from "@/components/ui/button"
import { Badge } from "@/components/ui/badge"
import Image from "next/image"
import { ArrowRight, Star } from "lucide-react"

export function Hero() {
  return (
    <section className="relative overflow-hidden py-20 lg:py-32">
      <div className="container mx-auto px-4">
        <div className="mx-auto max-w-3xl text-center">
          <Badge variant="secondary" className="mb-4">New: Feature X is here</Badge>
          <h1 className="text-4xl font-bold tracking-tight sm:text-5xl lg:text-6xl">
            Headline that speaks to the <span className="text-primary">pain point</span>
          </h1>
          <p className="mt-6 text-lg text-muted-foreground max-w-2xl mx-auto">
            Supporting copy that explains the value proposition in one clear sentence. Focus on outcomes, not features.
          </p>
          <div className="mt-8 flex flex-col sm:flex-row gap-4 justify-center">
            <Button size="lg" className="text-lg px-8">
              Primary CTA <ArrowRight className="ml-2 h-5 w-5" />
            </Button>
            <Button size="lg" variant="outline" className="text-lg px-8">
              Secondary CTA
            </Button>
          </div>
          {/* Social proof strip */}
          <div className="mt-10 flex flex-col items-center gap-3">
            <div className="flex -space-x-2">
              {[1,2,3,4,5].map(i => (
                <Image key={i} src={`/avatars/${i}.jpg`} alt="" width={32} height={32} className="rounded-full border-2 border-background" />
              ))}
            </div>
            <div className="flex items-center gap-1">
              {[1,2,3,4,5].map(i => <Star key={i} className="h-4 w-4 fill-yellow-400 text-yellow-400" />)}
              <span className="ml-2 text-sm text-muted-foreground">Trusted by 10,000+ users</span>

          </div>
        </div>
      </div>
    </section>

  <div className="container grid gap-12 lg:grid-cols-2 items-center">
    <div>
      <h1>...</h1>
      <p>...</p>
      <Button>...</Button>
    </div>

        <div className="flex flex-wrap items-center justify-center gap-8 lg:gap-16 opacity-60">

      if (diff <= 0) { clearInterval(interval); return }
      setTimeLeft({
        days: Math.floor(diff / 86400000),
        hours: Math.floor((diff % 86400000) / 3600000),

        seconds: Math.floor((diff % 60000) / 1000),
      })
    }, 1000)
    return () => clearInterval(interval)
  }, [targetDate])

  return (
    <div className="flex gap-4 justify-center">
      {Object.entries(timeLeft).map(([label, value]) => (
        <div key={label} className="text-center">
          <div className="text-3xl font-bold tabular-nums">{String(value).padStart(2, "0")}</div>
          <div className="text-xs text-muted-foreground uppercase">{label}</div>

              <CardContent className="pt-6">
                <f.icon className="h-10 w-10 text-primary mb-4" />
                <h3 className="font-semibold mb-2">{f.title}</h3>

          <span>{b.label}</span>
        </div>
      ))}
    </div>
  )
}
```

## Page Layout Pattern

```tsx
// Typical high-converting landing page order:
// 1. Hero (with primary CTA)
// 2. Logo strip (social proof)
// 3. Problem → Solution (before/after)
// 4. Feature grid or bento
// 5. Testimonials
// 6. Pricing
// 7. FAQ
// 8. Final CTA section
// 9. Trust badges + footer
```

## Conversion Best Practices

1. One primary CTA per viewport — don't compete with yourself
2. Sticky CTA on mobile (fixed bottom bar)
3. Above-the-fold must contain: headline, value prop, CTA, social proof
4. Use `priority` on hero images for LCP
5. Repeat CTA after every 2-3 sections
6. Use urgency/scarcity sparingly and honestly
7. Test button copy > test button color
