Body node ID class module is used to add node ID (nid) and node type as a class to <body> tag on node pages.
In Drupal 7 core there was a unique node ID class in the <body> tag.
This is forward-port of that functionality for Drupal 8.

Installation

Install as you would normally install a contributed Drupal module.

Configuration

This module works out of the box, once you enable it there is no need to configure anything, except clear your caches.
Node ID will show up in <body> tag as "page-node-{nid}"
and Node Type will show up as "page-node-type-{bundle}" which is equivalent to Drupal 7 core functionality.

Usage

This module is useful for cases when specific pages need custom styling.
Target page using unique node ID as following CSS class (replace 123 with targeted node ID):

.page-node-123{ }
