Description: 

Previously in the Classy theme when viewing a node page you would have a body class like this, if the node is an article for example:

node--type-article

This conflicted with an identical class on each node's <article> tag and did not meet Drupal 8 CSS standards because there is no 'node' component on the body and we don't consider the body to be a component either.

For these reasons the class has been changed to (again using article as an example):

page-node-type-article
