A client asked for a better was to warn editors if they are viewing a revision.

I'm not sure how important it will be for this client to tell the difference between a unpublished node and a revision, but I can see where it might be helpful.

We have a class for "unpublished" content and use that to provide some light shading behind content that is NOT yet published. How about a class for "revisions"? 

I'm not seeing any. Is there an easy way to add that class, without custom code?

Hi Tim. Yes I think at the moment it needs custom code: 

/**
 * Implements hook_preprocess_node().
 */
function theme_name_preprocess_node(&$variables) {
  if (!$variables['is_active_revision']) {
    $variables['classes'][] = 'not-active-revision';
  }
}

It may also be possible to do without that function doing a wildcard search for part of a class as there seem to be classes that include the word revision.

There is now a module to help with this.
https://backdropcms.org/project/revision_helper 

The module allows site editors to select a custom color to display on revisions of nodes, much in the way backdrop puts a background color on unpublished nodes.



It also enables a "warning" message on revision pages. This can be disabled through settings.
