What is the purpose of the <main> tag in an HTML document?

The

tag in an HTML document is designed specifically to represent the dominant content of the body of that document. This tag helps to define the primary content that is unique to the page, distinguishing it from other sections such as headers, footers, or sidebars.

Using the

tag improves accessibility for screen readers and enhances the semantic structure of the HTML document, allowing both users and search engines to identify the central content more easily. This focus on the main content is crucial for providing an optimal user experience, as it allows for better navigation and understanding of the webpage.

The other options relate to different HTML elements and their functions. For example, the representation of sidebar content would correspond to tags such as

tag, which is solely dedicated to the primary content.
