The Cart is usually the last step in the shopping before the shopper starts the checkout process, except if you've enabled the Skip Cart add-on.
In Debutify Shopify themes, there are various ways to view the shopping cart. You can set it up as either a drawer (pulls out of the page), to redirect to a cart page, or as a pop-up on the screen.
How to Change the Cart Type
In Shopify admin, under Online Store, click on themes.
Select your Debutify Shopify theme and click on Customize.
Click on the Theme Settings icon.
Click on Cart.
Select a cart type.
Click Save to apply the changes.
