HTML, short for HyperText Markup Language, is the foundation for all web pages and websites. HTML files contain the basic structure of a web page, but they can also contain references to other resources, such as CSS for styling and JavaScript for interactivity. HTML files can be viewed with browsers, which interpret the code and display it to the user.
