CSS: Here you can enter CSS (Cascading Style Sheet) commands to apply to your printable invoice and print template. These commands allow customisation of many aspects of the way the HTML page appears in a web browser and is printed. Your CSS commands will be included in the head section of the HTML invoice.
To find examples of what can be done go to this document: Custom CSS.
