.Create your own classes or modify existing classes in a report to format objects across a report according to your particular needs. In Report Studio, 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. In addition, some classes can be used to format Query Studio reports.
From the File menu, click Report Properties.
Click Report styles and select one of the following options:
To work with classes in the default style sheet, click Default styles.
To work with classes that were used in Cognos ReportNet, click Use 1.x report styles.
Use 1.x report styles when you are working with reports created in ReportNet and you want to preserve their original appearance.
To work with classes that have minimal styling defined, click Simplified styles.
This option is useful when creating financial reports.
Pause the pointer over the page explorer button 
and click Classes.
To create a new class, in the Insertable Objects pane, drag Class to the Local Classes pane.
To modify an existing class, in the Local Classes or Global Class Extensions pane, click the class that you want.
Modify a global class to apply a change to all objects that use that class. For example, if you modified the style List column title cell, all column titles in lists will reflect your modifications.
Tip: Ctrl+click classes to make the same change to more than one class.
In the Properties pane, modify the properties to specify your desired formatting.
Tip: Look at the Preview pane to preview your changes for different report objects, such as blocks, table cells, and text items.
If you modify a global class, a pencil symbol appears beside the global class icon to indicate that the class was modified.
Apply the class to the objects you want:
Pause the pointer over the page explorer button, and click a report page.
Click an object to which you want to apply a class.
In the Properties pane, double-click the Class property.
Click the classes that you want to apply from the Local
classes and Global classes panes
and then click the right arrow button 
.
If you applied more than one class, in the Selected classes pane, specify the order in which the classes are applied by clicking each class and clicking the up or down arrow button.
Classes in the Selected classes pane are applied from top to bottom. The style properties from all classes are merged together when they are applied. However, if the classes have style properties in common, the properties from the last class applied override those from previous classes.
Click OK.
Some global classes are specific to Query Studio or can be applied to Query Studio reports. You can modify the following classes to format Query Studio reports.
Class | Description |
List column body cell | Style used to format list data. |
List column title cell | Style used to format list column headings. |
Create a Query Studio template .
Modify the global classes that you want.
Save the template.
To format a Query Studio report using the modified classes, the template must be applied to the report. For more information about applying a template to a Query Studio report, see the Query Studio User Guide.
In addition to creating or modifying classes in a report, you can create and modify classes that will apply to all reports. Default styles are stored in a style sheet named GlobalReportStyles.css. For information about modifying the style sheet, see the Administration and Security Guide.
