+## Overview
 
 Separators are automatically added in CSS through [`::before`](https://developer.mozilla.org/en-US/docs/Web/CSS/::before) and [`content`](https://developer.mozilla.org/en-US/docs/Web/CSS/content).
 
 {% example html %}
-<ol class="breadcrumb">
-  <li class="breadcrumb-item active">Home</li>
-</ol>
-<ol class="breadcrumb">
-  <li class="breadcrumb-item"><a href="#">Home</a></li>
-  <li class="breadcrumb-item active">Library</li>
-</ol>
-<ol class="breadcrumb">
-  <li class="breadcrumb-item"><a href="#">Home</a></li>
-  <li class="breadcrumb-item"><a href="#">Library</a></li>
-  <li class="breadcrumb-item active">Data</li>

-Similar to our navigation components, breadcrumbs work fine with or without the usage of list markup.

+  <ol class="breadcrumb">

-  <a class="breadcrumb-item" href="#">Data</a>

+## 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.
