XSL-FO zone

XSL-FO uses rectangular boxes (areas) to display output.

XSL-FO Regions

The XSL formatting model defines a series of rectangular regions (boxes) for displaying output.

All output (text, images, etc.) will be formatted into these boxes and then displayed or printed to a target medium.

Let's examine the following regions:

• Pages

• Regions

• Block areas

• Line areas

XSL-FO Pages (pages) contain regions (Regions).

XSL-FO Regions

• region-body (the body of the page)

• region-before (the header of the page)

• region-end (right column)

XSL-FO Regions (areas) contain block areas (Block Area).
