Hypertext Markup Language (.html)
The HTML (Hypertext Markup Language) file extension, is a fundamental file format in web development. It structures content on the web through the use of tags to create elements such as headings, paragraphs, links, and images. Originating from Tim Berners-Lee's work at CERN in the early 1990s, HTML has evolved to become the cornerstone of web design and development, facilitating the creation of dynamic and interactive web pages. HTML files are essential for displaying and structuring web content, ensuring a seamless user experience across various browsers and devices.
