Bootstrap JS Carousel
JS Carousel (carousel.js)
Il plug-in Carousel è un componente per scorrere gli elementi, come un carosello (presentazione).
Per un tutorial sui Carousel, leggi il nostro Bootstrap Carousel Tutorial .
Nota: i caroselli non sono supportati correttamente in Internet Explorer 9 e versioni precedenti (perché utilizzano transizioni e animazioni CSS3 per ottenere l'effetto diapositiva).
