Altering display mode for authoring information I'm trying to deal with authoring info for articles in Drupal 7. I've found the way to hide or unhide it, and that's all I can do. But what I'd need is find a way to display on certainly tagged articles, but hide when that specific tag is not added. Is there any solution for this without coding? CSS is okay, but I know no PHP.

Thank,
cs.
As you prefer css, checkout the module Field Formatter CSS Class


  The Field formatter CSS class module allows you to set any
  text/list/option/taxonomy field to render as CSS class on the node.
  This enables the node author to select predefined CSS styling per
  node.


Also Field Formatter Class


  This module allows site administrators to add classes to the outer
  HTML wrapper for any field display.


Then you can hide your info with css based on this unique class provided by either of these two modules
