It's also possible to use an **embedded SVG icon**. Apply it via our CSS custom property, or use the Sass variable.

### Using embedded SVG
Inlining SVG as data URI requires to URL escape a few characters, most notably `<`, `>` and `#`. That's why the `$breadcrumb-divider` variable is passed through our [`escape-svg()` Sass function]({{< docsref "/customize/sass#escape-svg" >}}). When using the CSS custom property, you need to URL escape your SVG on your own. Read [Kevin Weber's explanations on CodePen](https://codepen.io/kevinweber/pen/dXWoRw ) for detailed information on what to escape.

```
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;`.
