description	Generates a complete Astro 5 landing page with Tailwind CSS v4 from copywriting content. Triggers when the user asks to build a landing page, create the HTML/CSS for a landing page, generate an Astro site from copy, or implement a landing page design. Expects structured copywriting input matching the writing-landing-page-copy output format.

Building Landing Page

Generates a production-ready Astro 5 + Tailwind CSS v4 landing page from structured copywriting content.

Copy this checklist and track progress:

Build Progress:
- [ ] Phase 1: Copywriting input validated
- [ ] Phase 2: Project scaffolded (astro config, package.json, tailwind)
- [ ] Phase 3: Base layout and global styles created
- [ ] Phase 4: Navbar and Footer components created
- [ ] Phase 5: Section components generated from copy
- [ ] Phase 6: Index page assembled
- [ ] Phase 7: Build verified

Phase 1: Validate Input

Check that structured copywriting content exists. It should contain sections with this format:

## [Section Name]
> **Psychology**: [principle]
### Headline
### Subheadline / Supporting
### Body
### CTA (if applicable)

If no copywriting exists yet, suggest running the writing-landing-page-copy skill first.

Confirm with the user:

1. Project path: Where to generate the project
2. Brand customization: Logo text/SVG, primary color (default: #3b00ff), font (default: Inter), site URL, organization name
3. Sections to build: Which sections from the copy to implement

Phase 2: Scaffold Project

Generate the Astro 5 project. Follow the setup in project-setup.md exactly.

Create these files:

• package.json - Astro 5, Tailwind v4, Node adapter, sitemap
• astro.config.mjs - SSR mode with Node adapter + Tailwind vite plugin
• tsconfig.json - Strict mode with @/ path alias
• src/styles/global.css - Tailwind v4 imports + theme variables

Run bun install after scaffolding.

Phase 3: Base Layout and Global Styles

Create src/layouts/Base.astro with:

• Full SEO meta tags (OG, Twitter, canonical)
• Google Fonts link (Inter by default)
• JSON-LD Organization schema (use site URL and organization name from Phase 1)
• Global CSS classes for effects (gradient-text, btn-glow, card-hover, hero-glow)
• <slot /> for page content

Follow the design system defined in design-system.md for all color tokens, typography, spacing, and effect classes.

Phase 4: Navbar and Footer

Create src/components/Navbar.astro:

• Sticky with backdrop-blur
• Desktop nav links (one per section) + mobile hamburger toggle
• Primary CTA button on the right
• Client-side JS for mobile menu toggle

Create src/components/Footer.astro:

• Logo + tagline
• Social/external links
• Copyright line

Phase 5: Section Components

For each section in the copywriting input, generate a corresponding .astro component. Follow the component patterns in components.md for structure, props, and Tailwind classes.

Map copywriting sections to components:

Copy Section	Component	Key Pattern
Hero	Hero.astro	Glow background, gradient text, primary CTA button
Trust Bar	TrustBar.astro	Monochrome logo row, "Trusted by X" context
Loss Aversion	PainPoints.astro	3 pain cards with icons, dark bg, empathetic tone
Benefits	Benefits.astro	Rule-of-3 cards with icons, hover lift
Process	Process.astro	3 numbered steps, light bg, time estimates
Features	Features.astro	6-8 feature grid, icon + name + description
Pricing	Pricing.astro	2-3 tier cards, highlighted recommended, feature checklist
Testimonials	Testimonials.astro	Quote cards with attribution, avatar placeholder
FAQ	FAQ.astro	Native <details> accordion, chevron rotation
Final CTA	FinalCTA.astro	Repeat hero CTA, glow background, secondary link

Each component:

• Accepts props typed with a TypeScript interface
• Uses content from the copywriting directly as prop defaults
• Follows the alternating dark/light section pattern
• Includes responsive breakpoints (mobile-first, md: for desktop)

Phase 6: Assemble Index Page

Create src/pages/index.astro that imports and composes all section components in order:

---
import Base from "@/layouts/Base.astro"
import Navbar from "@/components/Navbar.astro"
import Hero from "@/components/Hero.astro"
// ... remaining sections
import Footer from "@/components/Footer.astro"
---

<Base title="...">
  <Navbar />
  <main>
    <Hero />
    <!-- sections in copywriting order -->
  </main>
  <Footer />
</Base>

Pass copywriting content as props or inline it directly in the component files.

Phase 7: Verify Build

Run:

bun run build

Fix any TypeScript or Tailwind errors. Verify the output renders correctly.

Example

Copywriting Hero input:

## Hero
> **Psychology**: Self-Interest (WIIFM) + Social Proof
### Headline
Ship 3x faster without breaking production
### Subheadline / Supporting
The CI/CD platform built for teams that move fast. Set up in 5 minutes, not 5 sprints.
### CTA
Start building free | No credit card required

Generated Hero.astro output:

---
interface Props {
  title?: string
  highlightedText?: string
  subtitle?: string
  ctaText?: string
  ctaHref?: string
  ctaMicrocopy?: string
}

const {
  title = "Ship 3x faster",
  highlightedText = "without breaking production.",
  subtitle = "The CI/CD platform built for teams that move fast.\nSet up in 5 minutes, not 5 sprints.",
  ctaText = "Start building free",
  ctaHref = "#pricing",
  ctaMicrocopy = "No credit card required",
} = Astro.props
