Style sheets (or Cascading Style Sheets) refer to HTML extensions that provide powerful formatting flexibility. With style sheet support, your HTML documents can include any of the following:
any font size or style
overlapping objects
horizontal and verical lines and rectangles of any color or width
precise object positioning on a page
pagination
printing from a Web browser
inline image maps
This means that the sophisticated formatting in a report is preserved when you format the report as an HTMLCSS document. Without style sheet extensions, your HTML documents display only basic text formats and imported images. With style sheets, images of highly formatted text can be replaced with text objects of equivalent style, color, and font. Text objects can be positioned to overlay image objects. All text is fully searchable, and fewer images have to be downloaded.
To view an HTML document that takes advantage of style sheets, you must display it in a browser that supports style sheets.
Using external style sheets for HTMLCSS output
Every corporate Web site today uses style sheets to enforce the corporate look-and-feel across Web pages. External style sheets are Cascading Style Sheet (CSS) files that are referenced by these Web pages. End users typically want the same style used in pages on their Web site applied to their Web reports.
In prior releases, applying style sheets and user-defined styles to reports involved manually editing the HTMLCSS output.
Beginning with Oracle Reports 10g Release 2 (10.1.2), you can specify user-defined styles and style sheets for HTMLCSS output using Reports Builder. Styles can be applied to report, frame, repeating frame, text, field, and file link objects using the new Style Sheets, CSS Class Name, and CSS ID properties. The generated HTMLCSS output includes links to the style sheets and the user-defined styles are applied to the objects.
The following elements are not supported by HTML style sheet extensions:
ellipses, arcs, polygons/polylines, and diagonal lines
rounded rectangles (formatted as rectangles)
arrows on lines
dashes on lines or borders of objects
