Alignment of field names & data

I’m trying to use “Company” & “Customer name” fields in print format builder on the bottom of the document as signature areas for my documents. But it will place data side by side and the alignment selection only has left or right. How do I change the positioning & is it possible to change the text size?

To customize alignment and size, you should insert custom HTML element and mention field and UI properties for it.

Is there an example somewhere I can follow?

Go to the print format builder and select Custom HTML as shown below.

You can edit it, change the field size, make it bold, etc. all in HTML as needed. It should appear something like as shown in the below screenshot.

Hope this helps.
