This component is a standalone component and can be used without the Bootstrap CSS.
Colors of the component are using the Bootstrap CSS vars (along with a default color) so that if you are using bootstrap the component will take your color palette.
You will need to import the styles defined in @agnos-ui/core-bootstrap/css/slider.css or @agnos-ui/core-bootstrap/scss/slider.scss
These styles are also exported in the global export @agnos-ui/core-bootstrap/css/agnosui.css or @agnos-ui/core-bootstrap/scss/agnosui.scss
