Landing Page (Vercel)

Create a production-ready static landing page with:

• Structure: Semantic HTML5 + Modern CSS + Vanilla JS
• Form: Working email capture (Formspree or custom endpoint)
• Analytics: Plausible/Fathom ready
• Design: Responsive, accessible, performant
• Deploy: One-click Vercel deployment

What Makes This Different

This skill generates working landing pages , not empty templates:

• Real email capture form that actually submits
• Analytics integration ready to activate
• Responsive design tested on mobile
• Accessibility basics (WCAG 2.1 AA)
• Content from your PRD brief

Workflow

Phase 1: PRD Brief Intake

Ask the user for product details , then extract and confirm:

I'll help you create a landing page. Based on your description:

**Product:** [Name]
**Tagline:** [One-line value proposition]

**Hero Section:**
- Headline: [Main headline]
- Subheadline: [Supporting text]
- CTA: [Button text]

**Features:** (3-5)
1. [Feature 1]: [Description]
2. [Feature 2]: [Description]
3. [Feature 3]: [Description]

**CTA Type:** [Waitlist / Sign Up / Demo Request / Contact]

**Social Proof:** [Testimonials / Logos / Stats / None]

Is this correct? Any adjustments?

Phase 2: Content Generation

Generate complete landing page content:

Sections:

1. Hero - Headline, subheadline, CTA button, optional hero image
2. Features - 3-5 feature cards with icons
3. How It Works - 3-step process (optional)
4. Social Proof - Testimonials or logos (optional)
5. FAQ - 4-6 common questions (optional)
6. CTA - Final call to action with form
7. Footer - Links, copyright, social icons

Phase 3: Form Integration

Email Capture Options:

1. Formspree (Recommended - Free tier)

   • No backend needed
   • Instant setup
   • Email notifications

2. Custom Endpoint

   • Your own API
   • Full control
   • Requires backend

3. Waitlist Service

   • Waitlist.email
   • Loops.so
   • ConvertKit

Phase 4: Quality Verification

Verify before handoff:

• HTML validates (W3C)
• Responsive on mobile
• Form submits successfully
• Analytics placeholders present
• Lighthouse score 90+

Usage

# Create landing page with PRD
python3 ~/.claude/skills/landing-page-vercel/scripts/scaffold.py \

Key Patterns

Form Handling (JavaScript)

document.addEventListener('DOMContentLoaded', () => {
  const form = document.getElementById('signup-form');
  const button = form.querySelector('button[type="submit"]');
  const messageEl = document.getElementById('form-message');

  form.addEventListener('submit', async (e) => {
    e.preventDefault();

    const originalText = button.textContent;

    try {
      button.textContent = 'Submitting...';
      button.disabled = true;

      const response = await fetch(form.action, {
        method: 'POST',
        body: new FormData(form),
        headers: { 'Accept': 'application/json' }
      });

      if (response.ok) {
        // Hide form and show success message
        form.style.display = 'none';
        messageEl.textContent = 'Thanks! We will be in touch.';
        messageEl.classList.add('success');
      } else {
        throw new Error('Form submission failed');
      }
    } catch (error) {
      button.textContent = originalText;
      button.disabled = false;
      messageEl.textContent = 'Something went wrong. Please try again.';
      messageEl.classList.add('error');
    }
  });
});

Data Structure (data.json)

{
  "name": "ProductName",
  "tagline": "Your compelling value proposition",
  "hero": {
    "headline": "Build something amazing",
    "subheadline": "The easiest way to create, launch, and grow your product.",
    "cta": "Join the Waitlist"
  },
  "features": [
    {
      "icon": "zap",
      "title": "Lightning Fast",
      "description": "Built for speed from the ground up."
    },
    {
      "icon": "shield",
      "title": "Secure by Default",
      "description": "Enterprise-grade security included."
    },
    {
      "icon": "sparkles",
      "title": "AI-Powered",
      "description": "Smart features that learn from you."
    }
  ],
  "faq": [
    {
      "question": "When will you launch?",
      "answer": "We're aiming for Q1 2026. Join the waitlist to be first to know."
    }
  ]
}

Form Integration Guide

Option 1: Formspree (Recommended)

1. Go to formspree.io
2. Create a free account
3. Create a new form
4. Copy your form ID
5. Replace YOUR_FORM_ID in the HTML

Option 2: Custom Endpoint

// In script.js, update the form action
const API_URL = 'https://your-api.com/api/waitlist';

form.addEventListener('submit', async (e) => {
  e.preventDefault();
  const email = form.querySelector('input[name="email"]').value;

  const response = await fetch(API_URL, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ email })
  });
  // Handle response...
});

Analytics Setup

Plausible (Privacy-friendly)

<!-- Add to head section -->
<script defer data-domain="yourdomain.com" src="https://plausible.io/js/script.js"></script>

Fathom

<!-- Add to head section -->
<script src="https://cdn.usefathom.com/script.js" data-site="YOUR_SITE_ID" defer></script>
