Error message

Unexpected end tag for "body", but there were unclosed elements

What it means

HTML parse error: </body> was reached while elements opened inside body were still on the stack of open elements (other than the expected body/html). The parser records the error and proceeds with the standard </body> handling, closing remaining content.
