PDF Templates - creating a border

Good Day.
I am attempting to create a pdf template with images interacting with text. I am specifically trying to create a border on the document, but not a standard border, a certificate type decorative border. The program is very bland and doesnt seem to accept any creative image addiiotns that work with the text. Does a CSS or Html not support this function in PDF templates.

Thank you

Hey,
I think you’re right in that the TinyMCE editor doesn’t allow for such extensive custom PDFs

I’ve had a look around and found that you might have some luck with either extending the mpdf functionality:

Or, perhaps, extending the tinymce functionality:

Or, if anyone else has some suggestions, they’d be much appreciated!
