HTML (HyperText Markup Language) is the standard markup language used to create and structure content on the World Wide Web. It defines the elements and structure of a web page, allowing browsers to render text, images, links, multimedia, and interactive elements.
The purpose of HTML is to provide a structured way to represent content so that browsers can interpret and display it correctly. While HTML defines the structure, CSS is used for styling and JavaScript is used for adding interactivity.
