Semantics
A landmark containing the main content of a document.
Additional info from the ARIA specification
This marks the content that is directly related to or expands upon the central topic of the document. The main role is a non-obtrusive alternative for "skip to main content" links, where the navigation option to go to the main content (or other landmarks) is provided by assistive technologies, or by a user agent or browser extension, through a keyboard shortcut or UI feature such as a side panel or dialog.
Assistive technologies SHOULD enable users to quickly navigate to elements with role main. user agents SHOULD treat elements with role main as navigational landmarks. user agents MAY enable users to quickly navigate to elements with role main.
The author SHOULD mark no more than one element on a page with the main role.
