HTML, CSS, and JavaScript are the core technologies of web development, each serving a distinct role but working together to create interactive, visually appealing, and structured web pages.
HTML (HyperText Markup Language) defines the structure and content of a webpage. It uses tags like <h1>, <p>, <div>, and semantic elements like <header> or <footer> to organize information.
CSS (Cascading Style Sheets) controls the presentation — colors, fonts, layouts, and responsiveness. It can be applied inline, internally within <style> tags, or externally via .css files.
JavaScript is a programming language that adds dynamic behavior and interactivity. It manipulates HTML and CSS through the DOM (Document Object Model), responds to user events, and can dynamically update styles or content.
