You can avoid adding breaks between topics to save space. By default, if a topic fits a page, it is distributed without any page breaks.

1. In the top-left corner, click the Main Menu and go to PDF Generator.
2. In the PDF Generator scenarios screen, click the publishing scenario you want to edit.
3. In the CSS tab, add this code.

   /* Break topics inside. */
   article {
       break-inside: auto;
   }
   /* Do not break chapter-level topics. */
   article:has(.topictitle1) {
       break-inside: avoid;
   }

4. Click Save Scenario.
5. Click the Select map to preview button to select the map you want to test with the updated scenario. Once selected, click the Generate PDF button.

Topics that are added below chapter-level are distributed without page breaks. This saves space in your publication.

You can decide which DITA elements are broken over multiple pages.

1. In the top-left corner, click the Main Menu and go to PDF Generator.
2. In the PDF Generator scenarios screen, click the publishing scenario you want to edit.
3. In the CSS tab, add this code. You can customize the code by assigning the specific DITA elements to either break-inside: auto or break-inside: avoid.

   /* Break the following elements over multiple pages: */
   .table,
   .code,
   .entry,
   .xref,
   .sysoutput,
   .varname,
   .filepath,
   .userinput,
   .stepxmp,
   .stepresult,
   .info,
   .dd,
   .result {
     break-inside: auto;
   }
   
   /* Avoid breaking the following elements over multiple pages: */
   .note,
   .dt,
   .title,
   .codeph,
   .userinput,
   .sysoutput,
   .fig,
   .abstract,
   .shortdesc,
   .example,
   .context,
   .prereq
   .postreq {
     break-inside: avoid;
   }

You can prevent breaking the definition title and definition description elements over multiple pages. To do that, you need to modify both your CSS and XSLT code in a PDF Generator scenario.

1. In the top-left corner, click the Main Menu and go to PDF Generator.
2. In the PDF Generator scenarios screen, click the publishing scenario you want to edit.
3. In the CSS tab, add this code:

   .dlentry {
     break-inside: avoid;
   }

4. In the XSLT tab, add this code under the <xsl:import> tag(s):

   <?xml version="1.0" encoding="UTF-8"?>
   <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
   
     <xsl:import href="/db/sdk2/internal/pdf_generator/pdf_generator.xsl"/>
   
   <!-- Add this code -->
     <!-- DL entry wrapper -->
     <xsl:template match="*[contains(@class, ' topic/dlentry ')]" name="topic.dlentry">
       <div class="dlentry">
         <xsl:apply-templates/>
       </div>
     </xsl:template>
   <!-- End of add this code -->
   
   </xsl:stylesheet>

5. Click Save Scenario.
6. Click the Select map to preview button to select the map you want to test with the updated scenario. Once selected, click the Generate PDF button.
