Introduction
Welcome to the exciting world of web development! Whether you're a complete beginner or making a career transition, this guide will help you understand the fundamental technologies that power the modern web.
The Three Pillars of Web Development
All websites are built on three core technologies:
- HTML (HyperText Markup Language) - Provides the structure and content
- CSS (Cascading Style Sheets) - Handles the styling and layout
- JavaScript - Adds interactivity and dynamic behavior
HTML Basics
HTML is the foundation of every website. It uses tags to structure content. For example, <h1> creates a heading, <p> creates a paragraph, and <a> creates a link.
Learning HTML is straightforward because the syntax is intuitive and forgiving. Start by creating simple pages and gradually explore more complex structures.
CSS for Styling
Once you have HTML content, CSS brings it to life with colors, layouts, and animations. CSS uses selectors to target HTML elements and apply styles to them.
Modern CSS includes features like Flexbox and Grid that make responsive design much easier than it used to be.
JavaScript for Interactivity
JavaScript is the programming language of the web. It runs in browsers and allows you to respond to user interactions, manipulate the DOM, and create dynamic experiences.
Don't be intimidated by programming! Start with small scripts and gradually build your confidence.
