``` This is HTML I'm using in the carousel. Add your own CSS according to this elements in `pointStyles`. check below guide for more details. ```html ``` - `inputs` is an `Input` and It accepts `NguCarouselConfig`. - `onMove` is an `Output` which triggered on every slide before start and it will emit `$event` as `NguCarouselStore` object. - `carouselLoad` is an `Output` which triggered when slide reaches the end on items based on inputs `load`. # Getstarted guide ## Banner with Custom point style ```javascript import { Component } from '@angular/core'; import { NguCarousel, NguCarouselStore } from '@ngu/carousel'; @Component({ selector: 'app-carousel', template: `
