Obj Region After
[ XSL-FO Reference Manual](#)
* * *
## Definition and Usage
The object defines the bottom area (footer) of a page.
XSL-FO uses the following elements to define page areas:
* defines the body area
* defines the top area (header)
* defines the bottom area (footer)
* defines the left area (left sidebar)
* defines the right area (right sidebar)
**Note:** region-before, region-after, region-start, and region-end are all part of region-body. To prevent text inside region-body from overlapping text in other areas, the margins of region-body must be at least as large as the dimensions of these four sub-areas.
**Note:** According to the XSL-FO 1.0 Recommendation standard, the padding and border-width properties must be set to 0.

### Example 1
XSL-FO uses page templates called "Page Masters" to define page layout. Each template must have a unique name:
In the above example, three elements define three different templates. Each template (page-master) has a distinct name.
The first template is named "intro". It can be used as a template for introductory pages.
The second and third templates are named "left" and "right". They can be used as templates for even-numbered and odd-numbered pages, respectively.
### Example 2
This is an excerpt extracted from an XSL-FO document:
The above code defines a "Simple Page Master Template" named "A4".
The page width is 297 mm and height is 210 mm.
All four page margins (top, bottom, left, right) are 1 cm each.
The body margin is 3 cm (on all four sides).
The before, after, start, and end regions of the body are each 2 cm.
The body width in the above example can be calculated as: page width minus left and right margins and the region-body margins:
297mm - (2 x 1cm) - (2 x 3cm) = 297mm - 20mm - 60mm = 217mm
Note that regions (region-start and region-end) are not included in this calculation. As previously explained, these regions are part of the body.
