Reply To: How to change CSS of “Thumbnails position” of product page

Good evening Luke,
It worked for pc, could you tell me how to get the same result from pc on mobile?

another doubt, these custom CSS can be placed inside the (“layouts” -> single product), inside the custom product page I’m creating, or does it need to be inside “Global Custom CSS” in Theme Settings -> Custom CSS, if I keep it inside layouts, does it affect performance or something else?
