What is the semantic purpose of the <header> tag in HTML5?

The

tag in HTML5 is designed to represent introductory content or navigational links that are typically associated with a particular section of the document or the entire page. It commonly contains elements such as headings, logos, author information, and navigation menus. This semantic purpose helps structure web content in a meaningful way, allowing search engines, browsers, and assistive technologies to better understand and navigate the content.

The

tag improves accessibility and search engine optimization (SEO) by clearly defining which parts of a webpage are intended for introductory information or navigation. This distinction makes it easier for users to locate important parts of the page and for machines to analyze the content accordingly. By using the

tag correctly, web developers can enhance both the usability and the meaning of their pages.
