How to style this in a component?

So i add this to my component like so
 `<div *ngIf="busy" class="container loading-container">
        <loaders-css [loader]="'ball-triangle-path'" [loaderClass]="'spinner'"></loaders-css>
    </div>`

Then in my code i can assign whatever i want to `spinner` - it only works with `::ng-deep` or global styles, so i can't style loaders differently in different components?
