Web Development Basics: Everything You Need to Know

If you’re new to coding or considering a career in tech, understanding the basics of web development is essential. Web development powers every website and web application you use, from simple blogs to large e-commerce platforms.

In this guide, we’ll cover everything you need to know about web development basics, including core concepts, tools, and how to get started.

What is Web Development?

Web development is the process of creating websites and web applications. It involves writing code, designing layouts, and configuring servers so that websites work properly.

There are two main types of web development:

  1. Frontend (Client-Side) – What users see and interact with in their browsers.

  2. Backend (Server-Side) – The server, database, and logic that make websites function.

Core Web Development Technologies

1. HTML (HyperText Markup Language)

HTML is the backbone of every website. It defines the structure of web pages using elements like headings, paragraphs, images, and links.

Example:

<h1>Welcome to Web Development</h1> <p>This is a paragraph of text on a website.</p>

2. CSS (Cascading Style Sheets)

CSS controls the appearance of web pages. It allows developers to add colors, layouts, fonts, and animations.

Example:

h1 { color: blue; text-align: center; }

3. JavaScript

JavaScript makes websites interactive. It allows you to create dynamic content, respond to user actions, and update elements without refreshing the page.

Example:

document.getElementById("btn").onclick = function() { alert("Hello, Web Developer!"); };

4. Backend Languages

Backend languages handle the server-side logic. Popular choices include:

  • PHP

  • Python

  • Node.js

  • Ruby

  • Java

Backend development manages:

  • Databases

  • User authentication

  • Server communication

  • Business logic

5. Databases

Databases store and organize data. Common databases include:

  • MySQL

  • PostgreSQL

  • MongoDB

  • SQLite

Example: Storing user data for login or e-commerce transactions.

Types of Web Development

  1. Frontend Development – User interface and experience.

  2. Backend Development – Server, database, and logic.

  3. Full-Stack Development – Both frontend and backend.

  4. CMS Development – Using platforms like WordPress or Shopify.

  5. Web Application Development – Building complex, interactive apps.
