To indicate the active page, apply aria-current="page" to the last breadcrumb link.
Apply aria-label="breadcrumb" to the nav element for proper accessibility.
Ensure the use of ol as the breadcrumb, as order matters in conveying the hierarchy.
<nav aria-label="breadcrumb">
<ol>
<li>
<a href="#accessibility">
Accessibility
</a>
</li>
<li>
<a href="#accessibility/nav">
Navigation
</a>
</li>
<li>
<a href="#accessibility/nav/breadcrumb" aria-current="page">
Breadcrumb
</a>
</li>
</ol>
</nav>
