This is my first post here! I did some searching and couldn't find anything related to this but I apologise in advance if there is a topic already.
We currently use ChannelAdvisor to manage our eBay store and Amazon Marketplaces and are looking to start to use their own standalone ecommerce solution as it is very useful and convenient to have them all managed from one central location. However I'm having a little trouble manipulating the store theme. There are a limited number of places to insert code but all code is accepted in these locations. I've gotten all of their custom CSS IDs and Classes and can adapt them but I am currently unable to resize and position any of the tables or do anything similar to this (they aren't assigned Classes or IDs, they're using the deprecated width/height attributes).
Is there anyone on here who's had any experience with this and can give me a few pointers?
