The MarginBox component allows you to position content in the margins of printed pages. It’s particularly useful for adding headers, watermarks, and other content that needs to appear in the margin areas of your printed documents.
For page numbers and footers, we recommend using the Footer component which provides built-in page numbering functionality.

​
Usage

The MarginBox component uses CSS Paged Media specifications to position content in specific margin boxes around your page. 
import { MarginBox } from "@htmldocs/react";

export default function Document() {
  return (
    <MarginBox 
      position="top-right" 
      runningName="document-title"
    >
      Quarterly Report
    </MarginBox>
  );
}
