Create and modify report and object styles
Create your own classes or modify existing classes in a report to format objects across a report according to your particular needs.
In IBM® Cognos® Analytics - Reporting, objects in reports are assigned a Cascading Style Sheet (CSS) class that provides a default style for the object. For example, when you create a new report, the report title has the class property Report title text assigned to it. In addition, objects inherit the classes set on their parent objects.
You can use classes to highlight data using conditional styles.
Classes you create or modify can be applied only to the current report. To create or modify classes for all reports, you must modify a layout style sheet.
