One of the most powerful features of styles is the ease with which you can change the look of a report. If you decide to change fonts or font sizes in the entire report, all you do is modify the style that controls the font properties. To modify a custom or imported style, in Outline, expand Styles, right-click the style, then choose Edit Style. All report elements that use that style are automatically updated to use the new formatting.

To modify styles in a linked CSS file, edit the CSS file that resides in the BIRT resource folder. When you save the edits, the report reflects the style changes.
