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 earlier versions of the Debutify theme, the cart could either be shown as a drawer (pulls out of the page), or the customer is redirected to a cart page.
There's now the option to set the cart as a pop-up (modal).
Drawer - Cart pulls out from the top of the page.
Page - Redirects the customers to a full-page cart.
Modal - Pop-up cart window.
