## 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.
|
|
|
|
{{< 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>
|
|
{{< /example >}}
|
|
|
|
## Dividers
|
|
|
|
Dividers are automatically added in CSS through [`::before`](https://developer.mozilla.org/en-US/docs/Web/CSS/::before) and [`content`](https://developer.mozilla.org/en-US/docs/Web/CSS/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.
|
|
|
|
{{< example >}}
|
|
<nav style="--bs-breadcrumb-divider: '>';" 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>
|
|
{{< /example >}}
|
|
|
|
When modifying via Sass, the [quote](https://sass-lang.com/documentation/modules/string#quote) function is required to generate the quotes around a string. For example, using `>` as the divider, you can use this:
|
|
|
|
```scss
|
|
$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.
|
|
|
|
{{< example >}}
|
|
<nav style="--bs-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");" 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>
|
|
{{< /example >}}
|
|
|
|
```scss
|
|
$breadcrumb-divider: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='8' height='8'%3E%3Cpath d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z' fill='currentColor'/%3E%3C/svg%3E");
|
|
```
|
|
|
|
You can also remove the divider setting `--bs-breadcrumb-divider: '';` (empty strings in CSS custom properties counts as a value), or setting the Sass variable to `$breadcrumb-divider: none;`.
|
|
|
|
{{< example >}}
|
|
<nav style="--bs-breadcrumb-divider: '';" 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>
|
|
{{< /example >}}
|
|
|
|
|
|
```scss
|
|
$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.
|
