I'm unable to identify how to change the styles of jBPM user task forms other than by plugging in CSS styles for individual fields (labels or content). (Even then, the documentation does explain where the CSS definitions must be deployed to be accessible from the forms.) But I'd rather not have to set CSS for each field individually if I can change them all globally to a common style. And no method is identified for changing overall form style properties (e.g., background-color). How can this best be accomplished? I'd prefer to do it separately for each project, but if I have to do it overall for all user task and process forms, that would be acceptable. The user documentation does not identify how to do this.
