Breadcrumb

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

Example

Use an ordered or unordered list with linked list items to create a minimally styled breadcrumb. Use our utilities to add additional styles as desired.

Breadcrumb - 图1

  1. <nav aria-label="breadcrumb">
  2. <ol class="breadcrumb">
  3. <li class="breadcrumb-item active" aria-current="page">Home</li>
  4. </ol>
  5. </nav>
  6. <nav aria-label="breadcrumb">
  7. <ol class="breadcrumb">
  8. <li class="breadcrumb-item"><a href="#">Home</a></li>
  9. <li class="breadcrumb-item active" aria-current="page">Library</li>
  10. </ol>
  11. </nav>
  12. <nav aria-label="breadcrumb">
  13. <ol class="breadcrumb">
  14. <li class="breadcrumb-item"><a href="#">Home</a></li>
  15. <li class="breadcrumb-item"><a href="#">Library</a></li>
  16. <li class="breadcrumb-item active" aria-current="page">Data</li>
  17. </ol>
  18. </nav>

Dividers

Dividers are automatically added in CSS through ::before and content. They can be changed by modifying a local CSS custom property --bs-breadcrumb-divider, or through the $breadcrumb-divider Sass variable — and $breadcrumb-divider-flipped for its RTL counterpart, if needed. We default to our Sass variable, which is set as a fallback to the custom property. This way, you get a global divider that you can override without recompiling CSS at any time.

Breadcrumb - 图2

  1. <nav style="--bs-breadcrumb-divider: '>';" aria-label="breadcrumb">
  2. <ol class="breadcrumb">
  3. <li class="breadcrumb-item"><a href="#">Home</a></li>
  4. <li class="breadcrumb-item active" aria-current="page">Library</li>
  5. </ol>
  6. </nav>

When modifying via Sass, the quote function is required to generate the quotes around a string. For example, using > as the divider, you can use this:

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

It’s also possible to use an embedded SVG icon. Apply it via our CSS custom property, or use the Sass variable.

Breadcrumb - 图3

  1. <nav style="--bs-breadcrumb-divider: url(&#34;data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='8' height='8'%3E%3Cpath d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z' fill='currentColor'/%3E%3C/svg%3E&#34;);" aria-label="breadcrumb">
  2. <ol class="breadcrumb">
  3. <li class="breadcrumb-item"><a href="#">Home</a></li>
  4. <li class="breadcrumb-item active" aria-current="page">Library</li>
  5. </ol>
  6. </nav>
  1. $breadcrumb-divider: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='8' height='8'%3E%3Cpath d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z' fill='currentColor'/%3E%3C/svg%3E");

You can also remove the divider setting --bs-breadcrumb-divider: ''; (empty strings in CSS custom properties counts as a value), or setting the Sass variable to $breadcrumb-divider: none;.

Breadcrumb - 图4

  1. <nav style="--bs-breadcrumb-divider: '';" aria-label="breadcrumb">
  2. <ol class="breadcrumb">
  3. <li class="breadcrumb-item"><a href="#">Home</a></li>
  4. <li class="breadcrumb-item active" aria-current="page">Library</li>
  5. </ol>
  6. </nav>
  1. $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.

For more information, see the WAI-ARIA Authoring Practices for the breadcrumb pattern.
