@use '~material-bottom-nav' as bottom-nav;

.bottom-nav {
  @include bottom-nav.root(
    $background-color: #009688,
    $active-color: #FFFFFF,
    $inactive-color: #E0E0E0
  );
}

Customization

The box-model and colors of the individual styles within this component can be configured by overriding the default variable values defined in bottom-nav.scss.

@use '~material-bottom-nav' as bottom-nav with (
  $destination-horizontal-padding: 4px, // reduce the horizontal padding within each destination
  $icon-font-size: 28px, // increase the icon size
);

.bottom-nav {
  @include bottom-nav.root(#009688, #FFFFFF, #E0E0E0);
}
