HTML, which stands for Hypertext Markup Language, is the standard language used to create and design documents on the World Wide Web. HTML defines the structure and layout of a web document by using a variety of tags and attributes. The correct structure of HTML consists of nested elements that include a head, which contains meta-information about the document, and a body, which contains the actual content like text, images, videos, and more. HTML elements are the building blocks of all websites, and they are essential for creating web pages that are functional, accessible, and visually appealing. HTML is written in the form of tags, enclosed in angle brackets, and it typically works in conjunction with CSS (Cascading Style Sheets) and JavaScript to create interactive and stylistically complex websites. The introduction of HTML5, the latest version, has brought new capabilities to the web, such as native video playback, improved support for graphic content, and better semantic elements that make the web more accessible and SEO-friendly. As the backbone of web design and development, understanding and using HTML is crucial for anyone looking to create or manage web content.
