HTML (HyperText Markup Language) is the foundational language used to create the structure and content of web pages. It uses a system of elements enclosed in tags (e.g., < h1 >, < p >, < a >) to define headings, paragraphs, links, images, and other components. HTML is organized in a hierarchical structure, starting with the < !DOCTYPE> declaration and the < html > root element, followed by < head > for metadata and < body > for visible content. Modern HTML (HTML5) introduces semantic tags like < header >, < footer >, and < article >, along with support for multimedia elements such as < audio > and < video >, making it more accessible and versatile for building dynamic, responsive web applications.
CSS (Cascading Style Sheets) is a styling language used to control the appearance of HTML elements on a web page. It allows you to define the layout, colors, fonts, spacing, and other visual aspects of a webpage, separating the content (HTML) from its presentation (CSS). CSS works by selecting HTML elements and applying specific styles to them using selectors and properties. For example, you can change the font of all headings using the font-family property, or adjust the layout of a page using flexbox or grid. CSS supports features like responsive design, animations, and transitions, enabling websites to look great across different devices and screen sizes.

JavaScript is a versatile, high-level programming language used to add interactivity, dynamic behavior, and functionality to web pages. It runs in the browser and enables features like form validation, interactive maps, animations, content updates without refreshing the page, and much more. JavaScript is an event-driven language, meaning it responds to user interactions like clicks, keypresses, or mouse movements. It works alongside HTML and CSS, providing a way to manipulate and modify content dynamically. Modern JavaScript (ES6 and beyond) supports features like arrow functions, classes, promises, and async/await for easier and more efficient development. Additionally, JavaScript frameworks and libraries like React, Angular, and Vue.js have become essential tools for building complex web applications.
Bootstrap is an open-source front-end framework designed to help developers build responsive, mobile-first websites and web applications quickly. It provides a set of pre-designed, reusable components such as navigation bars, buttons, forms, grids, and modals, along with a responsive grid system. Bootstrap uses HTML, CSS, and JavaScript to offer a wide range of layout options and UI elements that are optimized for various screen sizes and devices.Bootstrap is highly customizable, allowing developers to modify its default styles and components to suit their project's needs. It also includes built-in JavaScript plugins for features like carousels, tooltips, and popups. With its user-friendly design and extensive documentation, Bootstrap has become one of the most popular frameworks for building modern, professional websites efficiently.
