main
Definition and Usage
The HTML<main> tag is used to represent the main content area within an HTML 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.
The <main> tag surrounds the main content of the page - content that is unique to that document and is obviously the "main" content for that page. This excludes any content that is repeated across multiple pages (such as navigation bars, headers, footers, etc).
An HTML document can have a maximum of one <main> element. It must not appear within the <article> ,<aside>, <footer>, <header> or <nav> tags.
