While working on a custom bootstrap subtheme in Drupal, I needed to include specific classes in the body tag.
There are two different cases that I needed to take into consideration, one for nodes and one for custom paths generated by e.g. from Views or Taxonomy.
In the first case, I needed the node id to be included as a class, and on the second I needed a class name that was based on the path.
To achieve this, I needed to edit two different files under my subtheme category. You will need to replace themename with the actual name of your theme.
