The "text/html" media type is used to represent HTML (Hypertext Markup Language) documents. HTML is the standard language for creating web pages and web applications, allowing developers to structure content using elements like headings, paragraphs, links, and images. Browsers interpret "text/html" to render the content visually for users. When a web server sends a file with the "text/html" content type, it indicates that the file contains HTML code. This helps the browser understand how to display the information correctly. The use of "text/html" is essential for the functioning of the World Wide Web, enabling seamless navigation and interaction.
