HTML (Hypertext Markup Language) is the standard markup language used to create and structure content for the World Wide Web. HTML was first introduced in 1991 by Tim Berners-Lee and Robert Cailliau, and it has since evolved into a robust and widely-used language that forms the backbone of the internet.

HTML is a simple, declarative language that uses tags to define the structure and content of a web page. A tag is a simple command that is enclosed in angle brackets (< >), and it tells the web browser how to interpret the content that follows it. For example, the

tag is used to define a top-level heading, while the

tag is used to define a paragraph of text.

HTML documents are organized into a hierarchical structure of elements, with each element representing a different part of the page. For example, the element represents the entire document, while the element contains information about the document such as the page title and any links to external stylesheets or scripts. The element contains the main content of the page, and is where most of the page's content is defined.

One of the key features of HTML is its support for hyperlinks, which allow users to navigate between different web pages by clicking on a link. Hyperlinks are defined using the tag, and they can be used to link to other web pages, files, or email addresses.

HTML is a versatile language that can be used to create a wide range of web content, from simple static pages to complex web applications. HTML can be used in combination with other web technologies, such as CSS (Cascading Style Sheets) and JavaScript, to create dynamic, interactive web pages.

Over the years, HTML has evolved through several versions, with each version introducing new features and improvements. The latest version, HTML5, includes a wide range of new features such as support for multimedia content, new semantic elements, and improved support for mobile devices.

In summary, HTML is a powerful and widely-used language that forms the foundation of the World Wide Web. It provides a simple and easy-to-use way to structure and format web content, and it continues to evolve and improve to meet the needs of modern web development.
