What information is relayed to the web browser by html tags?

HTML tags provide structure and meaning to the content of a webpage by defining elements such as headings, paragraphs, links, images, and lists. They inform the web browser how to display the content, including its layout and formatting. For example, tags like <h1> denote the main heading, while <p> identifies a paragraph, guiding the browser in rendering the text appropriately. Additionally, attributes within tags can provide further information, such as linking to stylesheets or specifying image sources.
