Accessibility

Since breadcrumbs provide a navigation, it's a good idea to add a meaningful label such as aria-label="breadcrumb" to describe the type of navigation provided in the <nav> element, as well as applying an aria-current="page" to the last item of the set to indicate that it represents the current page.

For more information, see the WAI-ARIA Authoring Practices for the breadcrumb pattern.
