Highlight > Cart
Our theme has two options for the cart, one being a drawer (which opens each time a user adds something to the cart), the one one being a page (which means the user is redirected to the cart page).
Inside the cart you can choose the media aspect ratio of your products (thumbnails will be cropped to fit this design).
At the end, you can enable cart notes and show additional checkout buttons.
The additional checkout buttons can't be edited, they are created on the fly by Shopify based on your available payment methods and the current visitor's profile. Also, they will disappear after any change to the cart (adding more items, removing an item or changing the quantity).
