This page contains the knowledge base articles related to working with PDFs on Confluence.
If styling is not working as expected, it is useful to look at the HTML source to which the CSS is applied. Whenever an export is created with multiple pages, the intermediary HTML is stored in the temp directory in Confluence's home directory; i.e., <confluence-home>/temp/htmlexport-20110308-154047-1/export-intermediate-154047-2.html.
For Confluence Cloud users, you can make a Custom Space Export (HTML).
If an error is occurring, try to identify the specific page causing the problem. Hone in on the exact wiki markup; it's often a macro that isn't rendering properly.
