1. Introduction to Web Development
What is Web Development?
Web development refers to the process of creating websites and web applications that users can access via the internet. It encompasses everything from building simple static web pages to complex dynamic applications that interact with databases and APIs.
Frontend vs Backend Development
Frontend Development: Involves creating the visible parts of a website that users interact with, using HTML, CSS, and JavaScript.
Backend Development: Focuses on server-side programming, managing databases, and handling requests and responses between the frontend and backend.
Full Stack Development
Full stack developers are proficient in both frontend and backend technologies, capable of building entire web applications from scratch.
2. Understanding HTML: Building the Structure
Introduction to HTML
HTML (HyperText Markup Language) is the standard markup language for creating web pages. It provides the structure and content of web pages using elements and tags.
Basic HTML Structure
<!DOCTYPE html><html lang=”en”><head>
<meta charset=”UTF-8″>
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″>
<title>My First Web Page</title></head><body>
<header>
<h1>Welcome to My Website</h1>
</header>
<main>
<p>This is a paragraph of text.</p>
</main>
<footer>
<p>© 2024 My Website. All rights reserved.</p>
</footer></body></html>
Key HTML Elements
- <html>: Root element that wraps all content on the web page.
- <head>: Contains metadata and links to external resources.
- <body>: Main content area visible to users.
- Semantic Elements: Enhance the structure and meaning of content (<header>, <nav>, <main>, <footer>).
3. Styling with CSS: Designing Your Web Pages
Introduction to CSS
CSS (Cascading Style Sheets) is used to style and visually enhance HTML elements, defining layouts, colors, fonts, and more.
Basic CSS Example
/* styles.css */body {
font-family: Arial, sans-serif;
background-color: #f0f0f0;
margin: 0;
padding: 0;
}
header {
background-color: #333;
color: #fff;
text-align: center;
padding: 10px 0;
}
main {
max-width: 800px;
margin: 20px auto;
padding: 10px;
background-color: #fff;
border: 1px solid #ccc;
}
Linking CSS to HTML
<!DOCTYPE html><html lang=”en”><head>
<meta charset=”UTF-8″>
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″>
<title>Styled Web Page</title>
<link rel=”stylesheet” href=”styles.css”></head><body>
<header>
<h1>Welcome to My Styled Website</h1>
</header>
<main>
<p>This is a styled paragraph of text.</p>
</main>
<footer>
<p>© 2024 My Website. All rights reserved.</p>
</footer></body></html>
CSS Selectors and Properties
- Selectors: Target HTML elements (element, .class, #id).
- Properties: Define styles (color, font-size, margin, padding).
- Box Model: Understanding margin, border, padding, and content.
4. Adding Interactivity with JavaScript
Introduction to JavaScript
JavaScript is a versatile programming language used to add interactivity, manipulate HTML/CSS, and handle events on web pages.
Basic JavaScript Example
// script.jsdocument.addEventListener(‘DOMContentLoaded’, function() {
const button = document.querySelector(‘#click-me’);
button.addEventListener(‘click’, function() {
alert(‘Button clicked!’);
});
});
Linking JavaScript to HTML
<!DOCTYPE html><html lang=”en”><head>
<meta charset=”UTF-8″>
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″>
<title>Interactive Web Page</title>
<link rel=”stylesheet” href=”styles.css”>
<script src=”script.js” defer></script></head><body>
<header>
<h1>Welcome to My Interactive Website</h1>
</header>
<main>
<button id=”click-me”>Click Me</button>
</main>
<footer>
<p>© 2024 My Website. All rights reserved.</p>
</footer></body></html>
Handling Events and DOM Manipulation
- Event Listeners: Respond to user actions (click, submit, mouseover).
- DOM Manipulation: Update HTML/CSS dynamically (createElement, appendChild, classList).
5. Responsive Web Design and CSS Frameworks
Responsive Web Design (RWD)
RWD ensures web pages render well on various devices and screen sizes, enhancing user experience and accessibility.
CSS Frameworks
Frameworks like Bootstrap and Foundation provide pre-built CSS and JavaScript components for responsive layouts and UI design.
<!– Example using Bootstrap –><!DOCTYPE html><html lang=”en”><head>
<meta charset=”UTF-8″>
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″>
<title>Responsive Web Page</title>
<link rel=”stylesheet” href=”https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css”>
<script src=”https://code.jquery.com/jquery-3.5.1.slim.min.js”></script>
<script src=”https://cdn.jsdelivr.net/npm/@popperjs/core@2.5.3/dist/umd/popper.min.js”></script>
<script src=”https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/js/bootstrap.min.js”></script></head><body>
<div class=”container”>
<header class=”jumbotron text-center”>
<h1>Welcome to My Responsive Website</h1>
<p class=”lead”>Responsive design with Bootstrap</p>
</header>
<main class=”content”>
<div class=”row”>
<div class=”col-md-6″>
<h2>Section 1</h2>
<p>Lorem ipsum dolor sit amet…</p>
</div>
<div class=”col-md-6″>
<h2>Section 2</h2>
<p>Lorem ipsum dolor sit amet…</p>
</div>
</div>
</main>
<footer class=”text-center mt-4″>
<p>© 2024 My Website. All rights reserved.</p>
</footer>
</div></body></html>
Grid Systems and Responsive Design Principles
- Grid Systems: Use container, row, and col-* classes for flexible layouts.
- Media Queries: Adjust styles based on screen width (@media queries).
6. Introduction to Version Control with Git and GitHub
Version Control Basics
Version control systems like Git track changes to files over time, enabling collaboration and code management.
Setting Up Git
bash
# Install Git
sudo apt-get install git
# Configure Git
git config –global user.name “Your Name”
git config –global user.email “your.email@example.com”
GitHub: Hosting and Collaboration
GitHub is a platform for hosting Git repositories, facilitating collaboration, code review, and project management.
Creating Repositories: Initialize a new repository on GitHub and push local changes using git push.
Forking and Pull Requests: Contribute to open-source projects by forking repositories and proposing changes via pull requests.
7. Hosting Your Website: Domains and Web Hosting
Domain Names
Choose a domain name that reflects your website’s purpose and register it with domain registrars like GoDaddy or Namecheap.
Web Hosting Options
- Shared Hosting: Economical, suitable for small websites with moderate traffic.
- Virtual Private Server (VPS): Dedicated resources, more control and scalability.
- Cloud Hosting: Scalable, pay-as-you-go model, high availability (e.g., AWS, Google Cloud).
Deploying Your Website
Upload website files to your hosting provider via FTP or use deployment tools like rsync or CI/CD pipelines
