/**
 * NEB GPA Calculator - print styles.
 *
 * When the student presses "Print Result" only the marksheet is printed: site
 * navigation, the header, the footer, the calculator form, buttons and every
 * unrelated page element are removed from the printed output. The browser print
 * dialog provides "Save as PDF".
 *
 * The script moves the marksheet into a temporary #neb-print-root element
 * appended to <body> for the duration of the print call. Everything else is
 * then hidden with `display: none`, which - unlike `visibility: hidden` - does
 * not leave the rest of the page occupying space. That is what stops a blank
 * leading page and trailing blank pages appearing in the printout.
