LowyShin/giip-fde-agent

Static web development skill for beginners and non-developers. Covers HTML/CSS/JavaScript and Next.js App Router basics.

What is giip-fde-agent?

This skill is designed to help absolute beginners and non-developers create static websites with minimal friction. It supports two technology stacks: pure HTML/CSS/JavaScript for complete newcomers, and Next.js 14+ with Tailwind CSS for those ready to use a framework. The skill provides four main actions: `init` to scaffold a project with proper structure and configuration files (including CLAUDE.md and PDCA documentation), `guide` to analyze the current project and suggest next steps, and `help` to explain fundamental concepts and answer common questions. It works across all major AI agent platforms and is particularly useful for building portfolio sites, landing pages, or simple personal websites. The skill explicitly avoids backend features like login, databases, or payment processing, and automatically triggers when keywords related to beginner web development are detected in multiple languages.

Core Concept Explanations

HTML (Web Page Structure)

<!-- Basic structure -->
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>My Website</title>
    <link rel="stylesheet" href="css/style.css">
</head>
<body>
    <header>Header</header>
    <main>Main content</main>
    <footer>Footer</footer>
</body>
</html>

CSS (Styling Web Pages)

/* Basic styles */
body {
    font-family: 'Inter', sans-serif;
    margin: 0;
    padding: 0;
}

/* Center alignment */
.container {
    max-width: 1200px;
    margin: 0 auto;
    padding: 20px;
}

/* Responsive (mobile support) */
@media (max-width: 768px) {
    .container {
        padding: 10px;
    }
}

Next.js App Router (Creating Pages)

// app/page.tsx - Main page
export default function Home() {
  return (
    <main className="container mx-auto p-4">
      <h1 className="text-3xl font-bold">
        Welcome!
      </h1>
    </main>
  );
}

// app/about/page.tsx - About page
// URL: /about
export default function About() {
  return (
    <div className="container mx-auto p-4">
      <h1>About</h1>
      <p>I am ...</p>
    </div>
  );
}

Tailwind CSS (Quick Styling)

// Frequently used classes
<div className="
  container    // Center alignment
  mx-auto      // Auto left/right margin
  p-4          // Padding 16px
  text-center  // Center text
  text-xl      // Large text
  font-bold    // Bold text
  bg-blue-500  // Blue background
  text-white   // White text
  rounded-lg   // Rounded corners
  hover:bg-blue-600  // Color change on hover
">
