I have a few forms that on submission they generate a PDF. I use the MPDF library. For the first form, the generation of PDF considers the custom_css.php file and it adds style to the PDF. For the second form, I have duplicated the PDF layout and assigned as the PDF for that form. But whatever I try, when it comes to produce the PDF it just ignores the css. If I set this PDF template as the layout for the Details view, the css is applied in the document. But for the PDF it is ignored. The custom_css.php is the same is the one for the first form. This one has baffled me and I don't know what else I should look. Any ideas?
