🌐 What is Web Development?

Web Development is the process of building websites and web applications — the tools and platforms you use every day like YouTube, Facebook, Amazon, or even small personal blogs.

There are two major areas of web development:

🔹 1. Frontend (Client-side)

This is everything the user sees and interacts with in their browser — , colors, text, forms, images, and layout.

Main Technologies Used in Frontend:

✅ HTML (HyperText Markup Language)

HTML Example
<h1>Welcome to My Site</h1>
                    <p>This is a paragraph.</p>

✅ CSS (Cascading Style Sheets)

CSS Example
h1 {
                      color: blue;
                      font-family: Arial;
                    }

✅ JavaScript

JavaScript Example
alert("Welcome to my site!");

🔹 2. Backend (Server-side)

The backend is everything that runs behind the scenes — logic, databases, and servers. It powers features like logging in, saving comments, or processing payments.

Common Backend Technologies:

✅ Python (Django, Flask)

✅ PHP

✅ Node.js (JavaScript on the backend)

✅ Databases
