Breadcrumb

Indicate the current page's location within a navigational hierarchy that automatically adds separators via CSS.

example

<nav aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item active" aria-current="page">Home</li>
  </ol>
</nav>

<nav aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>

<nav aria-label="breadcrumb">
  <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" aria-current="page">Data</li>
  </ol>
</nav>

Changing the separator

Separators are automatically added in CSS through ::beforeand content. They can be changed by changing $breadcrumb-divider. The quote function is needed to generate the quotes around a string, so if you want >as seperator, you can use this:

$breadcrumb-divider: quote(">");

It's also possible to use a base64 embedded SVG icon :

$breadcrumb-divider: url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSI4IiBoZWlnaHQ9IjgiPjxwYXRoIGQ9Ik0yLjUgMEwxIDEuNSAzLjUgNCAxIDYuNSAyLjUgOGw0LTQtNC00eiIgZmlsbD0iY3VycmVudENvbG9yIi8+PC9zdmc+);

The separator can be removed by setting $breadcrumb-dividerto none:

$breadcrumb-divider: none;

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.
