HTML (HyperText Markup Language) is the standard markup language for creating web pages. It provides the structure and content of a webpage, defining elements such as headings, paragraphs, lists, links, images, and more. HTML uses tags, which are enclosed in angle brackets (< and >), to define these elements. These tags tell web browsers how to display the content. HTML documents are plain text files that can be created and edited using any text editor. Browsers interpret the HTML code and render the webpage accordingly. HTML forms the foundation of the World Wide Web, and it is often used in conjunction with CSS (Cascading Style Sheets) for styling and JavaScript for interactivity to create dynamic and visually appealing websites. Modern HTML, often referred to as HTML5, includes new features and APIs for multimedia, graphics, and offline storage, making it a powerful tool for web development. It's a crucial skill for anyone involved in web design or development, as it's the backbone of almost every website you encounter.
