  • Foundation for advanced skills - Launch pad for frameworks and libraries

Prerequisites: Getting Ready

Before starting, you should have basic understanding of:

  • HTML structure and tags
  • CSS styling and selectors
  • JavaScript variables and functions

Don't worry if you're new - we'll cover everything!

Building the Website

Step 1: Create an HTML File

  1. Open VS Code or your preferred editor.
  2. Create a new file and name it index.html.
  3. Copy and paste the following code:
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My First Webpage</title>
    <style>
        body { font-family: Arial, sans-serif; background-color: #f0f0f0; color: #333; margin: 0; padding: 0; }
        header { background-color: #4CAF50; color: white; text-align: center; padding: 1rem; }
        section { padding: 20px; text-align: center; }
        button { background-color: #4CAF50; color: white; border: none; padding: 10px 20px; cursor: pointer; }
        footer { background-color: #333; color: white; text-align: center; padding: 1rem; }
    </style>
</head>
<body>
    <header>
        <h1>Welcome to My First Webpage</h1>
    </header>
    <section>
        <p>Click the button below for a surprise!</p>
        <button onclick="displayMessage()">Click Me</button>
    </section>
    <footer>
        <p>&copy; 2024 Your Name</p>
    </footer>
    <script>
        function displayMessage() {
            alert("Hello! Welcome to the world of web development!");
        }
    </script>
</body>
</html>

Step 2: Run Your Code

  1. Save the File: After pasting the code, save the file as index.html.
  2. Locate the File: Navigate to the location where you saved the file.
  3. Open in Browser: Double-click the file to open it in your default web browser.

If everything is correct, you should see your first webpage in the browser. Click the button to see the JavaScript in action!

Understanding the Web Development Fundamentals

How Websites Work: The Big Picture

Browser Request
    ↓
Server Responds
    ↓
Browser Downloads HTML, CSS, JavaScript
    ↓
Browser Renders HTML (Creates DOM)
    ↓
CSS Styles Elements
    ↓
JavaScript Adds Interactivity
    ↓
User Sees Beautiful, Interactive Website

The Three Pillars of Web Development

  1. HTML (HyperText Markup Language)

    • Structure and content
    • Semantic meaning
    • Accessible markup

  2. CSS (Cascading Style Sheets)

    • Visual presentation
    • Layout and positioning
    • Responsive design

  3. JavaScript

    • Interactivity and behavior
    • DOM manipulation
    • Event handling

Deep Dive: HTML Structure

Understanding HTML Semantics

<!-- NOT SEMANTIC - DON'T DO THIS -->
<div class="header">
  <div class="logo">Brand</div>
  <div class="nav">Menu</div>
</div>

<!-- SEMANTIC - CORRECT APPROACH -->
<header>
  <figure>
    <img src="logo.png" alt="Brand Logo">
  </figure>
  <nav>
    <a href="/">Home</a>
    <a href="/about">About</a>
    <a href="/contact">Contact</a>
  </nav>
</header>

Building a Complete Page Structure

<!DOCTYPE html>
<html lang="en">
<head>
  <!-- Meta tags for browser and search engines -->
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta name="description" content="My awesome first website">
  <meta name="keywords" content="web development, learning, portfolio">
  
  <title>My First Website</title>
  <link rel="stylesheet" href="styles.css">
  <link rel="icon" href="favicon.ico">
</head>

<body>
  <!-- Navigation -->
  <nav class="navbar">
    <h1 class="logo">MyBrand</h1>
    <ul class="nav-links">
      <li><a href="#home">Home</a></li>
      <li><a href="#about">About</a></li>
      <li><a href="#projects">Projects</a></li>
      <li><a href="#contact">Contact</a></li>
    </ul>
  </nav>

  <!-- Main content -->
  <main>
    <!-- Hero section -->
    <section id="home" class="hero">

      <button id="ctaButton">Get Started</button>
    </section>

    <!-- About section -->
    <section id="about" class="about">
      <h2>About Me</h2>
      <p>This is where I share my story and interests...</p>
    </section>

    <!-- Projects section -->
    <section id="projects" class="projects">
      <h2>My Projects</h2>
      <div class="project-grid">
        <article class="project-card">
          <h3>Project 1</h3>
          <p>Description of my first project</p>
        </article>

      <h2>Get in Touch</h2>
      <form id="contactForm">
        <input type="email" placeholder="Your Email" required>
        <textarea placeholder="Your Message" rows="5" required></textarea>
        <button type="submit">Send Message</button>
      </form>
    </section>
  </main>

  <!-- Footer -->
  <footer>
    <p>&copy; 2024 My Website. All rights reserved.</p>
  </footer>

  <script src="script.js"></script>
</body>
</html>

CSS: Making it Beautiful

Mobile-First Responsive Design

/* Mobile first - these styles apply to all devices */
body {
  font-family: 'Segoe UI', Roboto;
  margin: 0;
  padding: 0;
  line-height: 1.6;
  color: #333;
}

.navbar {
  background-color: #333;
  color: white;
  padding: 1rem;
  position: sticky;
  top: 0;
}

.hero {
  background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
  color: white;
  padding: 2rem;
  text-align: center;
}

.hero h1 {
  font-size: 2rem;
  margin-bottom: 1rem;
}

.project-grid {
  display: grid;
  grid-template-columns: 1fr;
  gap: 1rem;
}

.project-card {
  border: 1px solid #ddd;
  padding: 1.5rem;
  border-radius: 8px;
  transition: all 0.3s ease;
}

.project-card:hover {
  box-shadow: 0 4px 12px rgba(0,0,0,0.1);
  transform: translateY(-5px);
}

/* Tablet devices (≥768px) */
@media (min-width: 768px) {
  .hero h1 {
    font-size: 3rem;
  }

  .project-grid {
    grid-template-columns: repeat(2, 1fr);
  }
}

/* Desktop devices (≥1024px) */
@media (min-width: 1024px) {
  .hero h1 {
    font-size: 4rem;
  }

  .project-grid {
    grid-template-columns: repeat(3, 1fr);
  }

  .navbar {
    display: flex;
    justify-content: space-between;
    align-items: center;
  }
}

JavaScript: Adding Interactivity

Making Your Website Interactive

// DOM Manipulation
const ctaButton = document.getElementById('ctaButton');
const contactForm = document.getElementById('contactForm');

// Event Listeners
ctaButton.addEventListener('click', function() {
  alert('Welcome! Let\'s build something awesome!');
  // Scroll to projects section
  document.getElementById('projects').scrollIntoView({ behavior: 'smooth' });
});

// Form Handling
contactForm.addEventListener('submit', function(e) {
  e.preventDefault(); // Prevent page reload
  
  const email = this.querySelector('input[type="email"]').value;
  const message = this.querySelector('textarea').value;
  
  console.log('Form data:', { email, message });
  
  // Show success message
  alert('Thank you for your message!');
  
  // Reset form
  this.reset();
});

// Smooth scrolling for navigation links
document.querySelectorAll('a[href^="#"]').forEach(anchor => {
  anchor.addEventListener('click', function(e) {
    e.preventDefault();
    const target = document.querySelector(this.getAttribute('href'));
    target?.scrollIntoView({ behavior: 'smooth' });
  });
});

// Mobile menu toggle (if you add a menu button)
const menuButton = document.querySelector('.menu-toggle');
const navLinks = document.querySelector('.nav-links');

if (menuButton) {
  menuButton.addEventListener('click', function() {
    navLinks.classList.toggle('active');
  });
}

Best Practices for Beginning Developers

✅ DO:

  • Write semantic HTML
  • Use meaningful class names (BEM naming convention)
  • Test on different screen sizes
  • Keep JavaScript modular
  • Use version control (Git)
  • Comment your code
  • Validate HTML and CSS

❌ DON'T:

  • Use <div> for everything
  • Write inline styles
  • Forget mobile responsiveness
  • Mix all JavaScript in one file
  • Ignore accessibility
  • Use outdated practices
  • Forget the viewport meta tag

Common Beginner Mistakes

Mistake 1: Not Testing on Mobile

/* Always include viewport meta tag! */
<meta name="viewport" content="width=device-width, initial-scale=1.0">

Mistake 2: Using Outdated HTML

<!-- OLD -->
<center><font size="5">Title</font></center>

<!-- NEW -->
<h1 style="text-align: center;">Title</h1>

<!-- BEST -->
<h1>Title</h1> <!-- Style with CSS -->

Mistake 3: Overly Complex JavaScript

// COMPLEX
document.addEventListener('DOMContentLoaded', function() {
  setTimeout(function() {
    // ...
  }, 100);
});

// SIMPLE
document.addEventListener('DOMContentLoaded', () => {
  // ...
});

Next Steps: Continue Learning
