-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).

+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.

+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:
