In a similar vein to the previous recipe, we will be looking at using the Drupal theme system's naming scheme to customize specific pieces of content. While the previous recipe targeted nodes of a particular node type, here we are going to target a single node based on its node ID.
The customization we will be performing on the node in question is that it should only display its content and links to authenticated users. In other words, anonymous users will only be able to see its title.
As we are going to be targeting a particular node based on its node ID, we will need to obtain this number from the node in question. This can be discerned from the URL of the node which should, by default, be of the form node/123
where 123 signifies the node ID. If the node has a URL alias enabled, this ID can be obtained by clicking on the Edit link of the node, which should lead us to a URL containing the node ID.
