 ## Changing the separator
 
 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/Sass/Script/Functions.html#quote-instance_method) function is needed to generate the quotes around a string, so if you want `>` as seperator, you can use this:
- 
+
 ```scss
 $breadcrumb-divider: quote(">");
 ```
