The WooCommerce Checkout template features two columns. The first column includes a multi-step process where customers can enter their billing and shipping details. The second column displays the cart section, allowing customers to review all items added to the cart and proceed with payment.
The multi-step functionality in the first column is implemented using the Bricks tab element to toggle between steps.

Note: We highly recommend moving any custom code to a code snippet plugin of your choice. Additionally, you can remove any unnecessary Bricks elements or styles as needed.
