## 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/functions/string#quote) function is needed to generate the quotes around a string, so if you want `>` as separator, you can use this:
|
|
|
|
```scss
|
|
$breadcrumb-divider: quote(">");
|
|
```
|
|
|
|
It's also possible to use a **base64 embedded SVG icon**:
|
|
|
|
```scss
|
|
$breadcrumb-divider: url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSI4IiBoZWlnaHQ9IjgiPjxwYXRoIGQ9Ik0yLjUgMEwxIDEuNSAzLjUgNCAxIDYuNSAyLjUgOGw0LTQtNC00eiIgZmlsbD0iY3VycmVudENvbG9yIi8+PC9zdmc+);
|
|
```
|
|
|
|
The separator can be removed by setting `$breadcrumb-divider` to `none`:
|
|
|
|
```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.
