Has anyone been able to create a watermark on exported PDFs from Confluence?
I'm able to get a custom footer to appear for each exported page but the watermark simply won't behave according to my custom CSS. I'm using the "PDF Stylesheet" box and trying to use a negative z-index and the transform function to create the word "Confidential" across the page diagonally, sitting just behind the main page content. I've even tried to use an embedded SVG, but that threw an error preventing it from exporting.
Is using custom CSS in the "PDF Stylesheet" box to create a watermark on PDFs exported from the Cloud version of Confluence simply not possible?
