The <main> tag specifies the main content of a document. The content inside the <main> element should be unique to the document.
It should not contain any content that is repeated across documents such as sidebars, navigation links, copyright information, site logos, and search forms.
With the help of tags, a web browser can distinguish between an HTML content and a simple content.
HTML tags contain three main parts: opening tag, content and closing tag.
The <main> element is used to denote the content of a webpage that relates to the central topic of that page or application. It should include content that is unique to that page and should not include content that is duplicated across multiple web pages, such as headers, footers, and primary navigation elements.
