# 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 `::before` and `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-divider` to `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.
