💡 What Is Web Development?
Web development is the process of building and maintaining websites. It includes everything from creating a simple static page to complex web applications, social media platforms, and e-commerce websites.
There are two main areas of web development:
Front-End (Client-Side): What users see — layout, colors, fonts, buttons.
Back-End (Server-Side): What users don’t see — servers, databases, application logic.
🧱 Key Front-End Technologies
Front-end development is all about creating the visual part of a website. The three core technologies are:
1. HTML (HyperText Markup Language)
Defines the structure of web pages. Think of it as the skeleton of a website.
<h1>Hello, world!</h1>
<p>This is a paragraph.</p>
2. CSS (Cascading Style Sheets)
Adds styles — colors, spacing, fonts, and layout. It's the makeup and clothing of your site.
h1 {
color: blue;
font-size: 2em;
}
3. JavaScript
Adds interactivity and dynamic behavior. It's the brain of your front-end application.
document.querySelector("button").onclick = () => alert("You clicked me!");
⚙️ What Is Back-End Development?
Back-end development handles data processing, authentication, database operations, and more. Common tools and technologies include:
Languages: Python, Node.js (JavaScript), PHP, Java
Databases: MySQL, MongoDB, PostgreSQL
Frameworks: Express.js, Django, Laravel
🛠️ Tools Every Web Developer Should Know
Text Editor: VS Code (most popular)
Version Control: Git and GitHub
Browser DevTools: Inspect, debug, test your code
Terminal / Command Line: For running scripts, installing packages
