## Changing the separator ## Dividers
Separators 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 changing `$breadcrumb-divider`. The [quote](https://sass-lang.com/documentation/modules/string#quote) function is needed to generate the quotes around a string, so if you want `>` as separator, you can use this: Dividers are automatically added in CSS through [`::before`](https://developer.mozilla.org/en-US/docs/Web/CSS/::before) and [`content`](https://developer.mozilla.org/en-US/docs/Web/CSS/content). They can be changed by modifying a local CSS custom property `--bs-breadcrumb-divider`, or through the `$breadcrumb-divider` Sass variable. 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 ```scss
$breadcrumb-divider: quote(">"); $breadcrumb-divider: quote(">");
``` ```
It's also possible to use an **embedded SVG icon**: It's also possible to use an **embedded SVG icon**. Apply it via our CSS custom property, or use the Sass variable.

<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">
<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 ```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"); $breadcrumb-divider: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='8' height='8'%3E%3Cpath d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z' fill='currentColor'/%3E%3C/svg%3E");
``` ```
The separator can be removed by setting `$breadcrumb-divider` to `none`: 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 ```scss
$breadcrumb-divider: none; $breadcrumb-divider: none;
