: Set template, when a bar/star is active or hovered.[ratingInactive]
: Set template, when a bar/star is inactive.[ratingFraction]

Here are some example:
Bootstrap rating example
<bar-rating [(rate)]="rate" [max]="5">
<ng-template ratingActive>
<i class="bi bi-star-fill" style="margin: 2px; color: #edb867"></i>
</ng-template>
<ng-template ratingInactive>
<i class="bi bi-star-fill" style="margin: 2px; color: #d2d2d2"></i>
</ng-template>
</bar-rating>
FontAwesome rating example
<bar-rating [rate]="rate" (rateChange)="onFaoRate($event)" [max]="10">
<ng-template ratingInactive>
<fa-icon [icon]="['far', 'star']" [fixedWidth]="true" size="lg" style="color: #d2d2d2"></fa-icon>
</ng-template>

</bar-rating>
Movie rating example
<bar-rating [(rate)]="rate" [max]="4" [theme]="'movie'" [showText]="true"

Predefined themes
If you want to use a custom rating template, you don't need to import any CSS theme.
If you want to use one of the predefined themes, you will need to import it in the global style style.scss
- Pure CSS stars (default)
[theme]="'default'"
@import '~ngx-bar-rating/themes/br-default-theme';
- Horizontal bars
[theme]="'horizontal'"
@import '~ngx-bar-rating/themes/br-horizontal-theme';
- Vertical bars
[theme]="'vertical'"
@import '~ngx-bar-rating/themes/br-vertical-theme';
- Custom stars
[theme]="'stars'"
@import '~ngx-bar-rating/themes/br-stars-theme';
- Movie rating
[theme]="'movie'"
@import '~ngx-bar-rating/themes/br-movie-theme';
- Square rating
[theme]="'square'"
@import '~ngx-bar-rating/themes/br-square-theme';
Rating style can be easily customized, check the classes used in any theme and add your own css.
You can also do the same for forms classes such as untouched, touched, dirty, invalid, valid ...etc
