Breadcrumb

Trail of links showing the current page's location in a hierarchy.

Use a semantic <nav> landmark.
Put .breadcrumb on the ordered list.
Use aria-current="page" for the current page.
Separators are generated with CSS (li + li::before).

<nav aria-label="Breadcrumb">
  <ol class="breadcrumb">
    <li><a href="/home">Home</a></li>
    <li><a href="/projects">Projects</a></li>
    <li><a href="/projects/docs">Docs</a></li>
    <li><a href="/current" aria-current="page">Breadcrumb</a></li>
  </ol>
</nav>
