From Shopnix Help
Shopnix supports the below standard (in-built) themes
The Azkaban theme is suitable for stores where shoppers spend a lot of time browsing through many items but eventually choose one or two items to purchase. Example: Shopping apparel or jewellery.
The Burrows theme is suited for items that are bought in groups. Example: groceries. Here shoppers browse multiple items, quickly add them to cart and finally proceed to checkout.
Choose a theme that suits your taste. You can choose/ change your theme under the section of the Store manager. We have designed the themes to ensure best shopper experience. Because of this the image dimensions in each theme is different. So choose your theme before uploading images to the store.
Once you choose a theme for your store you can choose a relevant color scheme for your store
