1. What is Web Development?

Web development is the process of building and maintaining websites and web applications. It encompasses everything from creating simple static pages to complex web apps like Facebook or Google.

How the Web Works (Simplified)

1. You Type a URL

Your browser sends a request to a server asking for a webpage.

2. Server Responds

The server sends back HTML, CSS, and JavaScript files.

3. Browser Renders

Your browser interprets the code and displays the webpage.

4. Interactive

JavaScript enables clicks, forms, and dynamic content.

Why Learn Web Development?

High Demand: Every business needs a web presence
Accessible: Free resources, no degree required
Creative: Build things people actually use
Remote-Friendly: Work from anywhere
Well-Paid: Competitive salaries globally

2. Frontend vs Backend vs Full Stack

Frontend Development

What users see and interact with. Building the visual interface and user experience. The "client-side."

Technologies: HTML, CSS, JavaScript, React, Vue

Backend Development

Server-side logic, databases, APIs. The "behind the scenes" that powers the application.

Technologies: Node.js, Python, Java, databases

Full Stack Development

Both frontend and backend. Can build complete applications independently. Most versatile role.

Technologies: All of the above

Recommendation: Start with frontend. It's more visual and immediately rewarding. Add backend later to become full stack.

3. HTML Fundamentals

HTML (HyperText Markup Language) is the structure of web pages. It defines the content—headings, paragraphs, images, links, and more.

Core HTML Concepts

Elements: <p>, <h1>, <div>, <img>
Attributes: id, class, src, href, alt
Semantic HTML: <header>, <nav>, <main>, <footer>
Forms: <input>, <button>, <select>

Essential HTML Elements

Element	Purpose	Priority
<h1>-<h6>	Headings (h1 most important)	🟢 Essential
<p>	Paragraphs of text	🟢 Essential
<a>	Links to other pages	🟢 Essential
<img>	Display images	🟢 Essential
<div>	Generic container	🟢 Essential
<ul>, <ol>	Unordered/ordered lists	🟢 Essential
<form>	User input forms	🟡 Important

Semantic HTML (Accessibility & SEO)

Use semantic elements instead of generic divs. They help screen readers and search engines understand your content.

<header> - Page or section header
<nav> - Navigation links
<main> - Main content area
<article> - Self-contained content
<section> - Thematic grouping
<footer> - Page or section footer

4. CSS Essentials

CSS (Cascading Style Sheets) controls the visual presentation—colors, fonts, layouts, spacing, and animations.

Core CSS Concepts

Selectors: Target elements (class, id, element)
Properties: What to change (color, font-size)
Values: How to change it (red, 16px)
Box Model: Margin, border, padding, content
Flexbox: One-dimensional layouts
Grid: Two-dimensional layouts

Essential CSS Properties

Property	Purpose	Category
color	Text color	Typography
font-size	Text size	Typography
margin / padding	Spacing	Box Model
display: flex	Flexible layouts	Layout
display: grid	Grid layouts	Layout
position	Element positioning	Layout

Modern CSS Layout: Flexbox & Grid

Master Flexbox and Grid—they're the most important CSS skills for modern layouts. Flexbox for rows/columns, Grid for complex layouts.

5. JavaScript Basics

JavaScript adds interactivity and dynamic behavior to websites. It's the programming language of the web.

Core JavaScript Concepts

Variables: let, const (avoid var)
Data Types: string, number, boolean, array, object
Functions: Reusable blocks of code
DOM Manipulation: Interact with HTML elements
Events: Respond to clicks, inputs, etc.
Async JavaScript: Fetch data, promises, async/await

JavaScript Learning Path

Variables, data types, operators
Control flow (if/else, loops)
Functions and scope
Arrays and objects
DOM manipulation and events
Fetch API and async programming
ES6+ features (arrow functions, destructuring)

Practice Tip: Build small interactive projects as you learn—a calculator, todo list, or quiz app. Learning by doing is essential for JavaScript.

6. Responsive Design

Responsive design ensures websites work on all screen sizes—phones, tablets, and desktops. It's a must-have skill.

Key Techniques

Media Queries

Apply different CSS rules based on screen size. @media (max-width: 768px)

Flexible Units

Use %, rem, em, vw instead of fixed pixels. Elements scale with the screen.

Mobile-First Approach

Design for mobile first, then add styles for larger screens. Modern best practice.

Breakpoints to Know

Mobile: < 768px
Tablet: 768px - 1024px
Desktop: 1024px+
Large Desktop: 1280px+

7. Frameworks & Libraries

CSS Frameworks

Tailwind CSS (Most Popular)

Utility-first CSS. Fast development, consistent design. Modern standard for many projects.

Bootstrap

Component-based framework. Quick prototyping. Still widely used but less popular with new projects.

JavaScript Frameworks

React (Most Jobs)

Most popular frontend framework. Component-based. Huge ecosystem. Learn this for most job opportunities.

Vue.js

Progressive framework. Easier learning curve than React. Popular in Asia and many startups.

Angular

Full framework by Google. Enterprise-focused. Steeper learning curve but powerful.
