Beginner's Guide to Coding

Introduction

Coding is the process of instructing computers to perform tasks by writing code in programming languages. It's how websites, apps, games, and automation come to life.

Why learn coding? Because it empowers you to build your ideas, understand technology deeply, and access countless career opportunities.

Examples include:

Creating websites like your favorite blogs or e-commerce stores.
Developing games that entertain millions.
Automating repetitive tasks to save time and reduce errors.

Tip: Stay curious! Explore different languages and build small things frequently to improve.

HTML Basics

HTML (HyperText Markup Language) structures your webpage. Think of it as the skeleton of a website, defining content like headings, paragraphs, links, and images.

Basic tags: <html>, <head>, <body>
Headings: <h1> to <h6>
Paragraphs: <p>
Links: <a href="">
Images: <img src="" alt="">

Mini Exercise: Create a simple HTML page with your name, an image, and a link to your favorite website.

CSS Basics

CSS (Cascading Style Sheets) adds style to your HTML, making pages colorful and nicely spaced. You control colors, fonts, layout, and more.

Properties: color, padding, margin, background
Select elements by tags, classes, or IDs
Create classes to reuse styles

Mini Exercise: Style your HTML page with colors, fonts, and spacing to make it visually appealing.

JavaScript Basics

JavaScript brings interactivity to websites — think buttons that respond, forms that validate, and animations.

Variables hold data
Functions perform actions
Events respond to user input
