HTML, or HyperText Markup Language, is the standard language used to create and design web pages. In the context of HTML 5 technology, it serves as the fundamental building block for structuring and presenting content on the web.

For instance, the tag is used to create paragraphs, to for headings, for links, and many more. Here's a basic example of an HTML 5 document structure: Document Title Main Heading This is a paragraph. Link to Example In this example, the ` ` declaration specifies that the document follows HTML 5 standards. The ` ` element encapsulates the entire document. The ` ` section contains meta-information such as the title of the page, while the ` ` section comprises the visible content. HTML 5 introduced new elements and attributes to enhance web development, including support for embedded multimedia, new form input types, and the element for rendering graphics. These advances have significantly enriched the capabilities of web applications. It's important to note that HTML is primarily responsible for the structure and content of a web page, and its styling and behavior are typically handled using CSS and JavaScript, respectively.
