Description🔵 .html (Hypertext Markup Language) The .html format is the standard markup language used for creating web pages and web applications. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document. It provides the basic building blocks for webpages, allowing for the integration of text, images, multimedia, and other elements. HTML files are the backbone of the World Wide Web and are interpreted by web browsers to display content.
Technical details🔵 The `.html` (HyperText Markup Language) format is a key technology for developing web pages and applications, enabling the structuring of web content. It uses tags to define elements like headings, paragraphs, links, and images within a webpage. HTML documents start with a doctype declaration, followed by ``, ``, and `` sections. HTML has evolved over the years, with HTML5 being the latest version that supports multimedia, semantic elements, and complex web application APIs. It uses character encodings like UTF-8 for worldwide character representation. HTML is typically used alongside Cascading Style Sheets (CSS) for visual styling and JavaScript for dynamic interactivity. Governed by the World Wide Web Consortium (W3C), HTML ensures consistent browser rendering and supports accessibility features for wider access. Its semantic tags also play a crucial role in search engine optimization (SEO). The combination of HTML's simplicity with CSS and JavaScript functionalities establishes it as a foundational element in web design and development.
