In this tuto, I'll share with you how to add body classes to 404 and 403 error pages in Drupal 8.

/**
 * @param $variables
 */
function THEMENAME_preprocess_html(&$variables)
{
    $statusCode = Drupal::request()->query->get('_exception_statuscode');
    if (isset($statusCode) and (($statusCode == 404) or ($statusCode == 403))) {
        $variables['attributes']['class'][] = 'page-' . $statusCode;
    }
}
