Custom Slider

In plain words: An Image Slider Carousel in LWC is an interactive UI component that displays a sequence of images or banners within a single contained space. Users navigate back and forth between slides using controls, while smooth CSS transforms shift the visible slide into view. Displaying rich media, product banners, or announcement graphics is a frequent requirement in custom Lightning apps, Experience Cloud portals, and dashboard homepages. While Salesforce offers the standard <lightning-carousel> base component, building a custom slider provides complete control over animation speed, transitions, custom navigation indicators, and responsive layouts.
