Native basis

An <aside> (or a <details> for the collapsible variant): the items as a list with a quantity badge on each thumbnail, then a <dl> of subtotal, discount, shipping and the total.

Web Platform APIs

<dl><details>:has()

Classes

.mk-order-summary.mk-order-summary-title.mk-order-summary-items.mk-order-summary-thumb.mk-order-summary-name.mk-order-summary-price.mk-order-summary-totals

Data attributes

data-variant="collapsible" (on a <details>).

§Default

The items with a quantity badge on each thumbnail, then the breakdown (<dl>): subtotal, discount, shipping and the total with VAT.

§Collapsible

data-variant='collapsible' on a <details>: on a small screen the summary shows only "Show order summary" and the total; it opens natively.
