∟Block Splitting for Page Break

This section provides a tutorial example showing a 'block' of text getting split into two parts, because it is too big to fit into remaining portion of the current page.

By default, if a "block" of text is too big to fit into the remaining portion of the "region-body" content area, it will be split into two parts to generate a page break. The first part is just big enough to fill the remaining portion of the current page, the second part goes to the beginning of the next page.

Here is my tutorial example, Block-Splitting-for-Page-Break.fo, that shows an "inline" formatting object getting split into two parts:

   margin="0.1in" page-height="2in" page-width="3in">
   <fo:region-body region-name="body" background-color="#eeeeee"/>
  </fo:simple-page-master>
 </fo:layout-master-set>
 <fo:page-sequence master-reference="page">
  <fo:flow flow-name="body">
   <fo:block margin="0.1in" padding="0.1in"
    border-width="1px" border-style="solid" 
    background-color="#ffeeff" 
    font-size="16pt" font-weight="bold">
    The Three Little Pigs
   </fo:block>
   <fo:block margin="0.1in" padding="0.1in"
    border-width="1px" border-style="solid" 
    background-color="#eeffff" text-align="justify">
    Once upon a time there were three little pigs who lived 
    with their Mother. 
    Early one morning they woke up and their mother said, 
    "you're too big for this house and its time you left home."
   </fo:block>
   <fo:block border-width="1px" border-style="solid"/>
  </fo:flow>
 </fo:page-sequence>
</fo:root>

You can process this example XSL-FO document with Apache FOP tool to generate pages in PDF format:

herong> fop -fo Block-Splitting-for-Page-Break.fo \
   -pdf Block-Splitting-for-Page-Break.pdf

When you open the PDF file, you should see the text block slit into two parts with the second part on the second page:

If you do want keep the "block" together on a single page, you can add the keep-together="always" attribute to the "block" element. Try it yourself.

If you want always to start a new page with a "block", you can add the break-before="page". Try it yourself.

If you want always to start a new page after a "block", you can add the break-after="page". Try it yourself.
