sectionA library can contain any number of themes, and a theme can contain any number of styles. You create themes in a library, then associate the library with a template. Actuate BIRT Designer Professional provides support for the following two types of styles:
Create a custom style, and apply it to a report element. For example, you can create a style named Report Title, then apply the style to a label that displays the report title.
Apply style properties to predefined style names, or selectors. These predefined style names correspond to the different types of report elements. For example, you can apply style properties to a predefined style named table-header, and all table headers in the report are formatted accordingly. This technique is similar to defining styles in CSS where you associate styles with HTML elements, such as <H1> or <P>.
