What is HTML, why it is used?

Ans. HTML, an acronym for Hyper Text Markup Language , is the predominant markup language for web pages.
It provides a means to describe the structure of text-based information in a document—by denoting certain text as links, headings, paragraphs, lists, etc.—and to supplement that text with interactive forms, embedded images, and other objects. HTML is written in the form of "tags" that are surrounded by angle brackets.
