Help with Product page on version 7.1

Site URL: https://antelope-cheetah-yx9z.squarespace.com/?password=Elena

Hello there

My client would like to build the product page with a static image on top, then a carousel just underneath on the left and a product description on the right. 

This is currently not possible within SquareSpace template. 

Is there a CSS code I can add in so that all the product pages I build look like the one attached?

Thank you very much in advance for your help!
