| Description | 🔵 HTML (Hypertext Markup Language) is the standard markup language used for creating web pages and web applications. It describes the structure of a web page semantically and originally included cues for the appearance of the document. HTML provides the basic building blocks for webpages, allowing for the integration of text, images, multimedia, and other elements. HTML files are essential for the World Wide Web and are interpreted by web browsers to display content. |
| Technical details | 🔵 The `.html` (HyperText Markup Language) format is a crucial technology for creating web pages and applications, allowing for the organization of web content. It utilizes tags to specify elements such as headings, paragraphs, links, and images within a webpage. HTML documents begin with a doctype declaration, followed by ``, ``, and `` sections. HTML has undergone changes over time, with HTML5 being the most recent version that supports multimedia, semantic elements, and intricate web application interfaces. It employs character encodings like UTF-8 for global character representation. HTML is commonly used in conjunction with Cascading Style Sheets (CSS) for visual design and JavaScript for interactive functionality. Regulated by the World Wide Web Consortium (W3C), HTML ensures consistent display across browsers and provides accessibility features for broader usage. Its semantic tags also play a significant role in search engine optimization (SEO). The fusion of HTML's simplicity with CSS and JavaScript capabilities establishes it as a fundamental element in web design and development. |
