This depends on the Theme in place, and the code that theme has. It's hard to guide you here without some context on what you have.

Hi Jason, 

Thank you for your message. I use the Debut theme. I know how to access the code and I know what code line I need to insert but I don't know where in the code to insert it to make sure it appears in the right place - in this case in the product description, left aligned. Thank you
