Carrossel Bootstrap JS
Carrossel JS (carousel.js)
O plugin Carousel é um componente para percorrer elementos, como um carrossel (apresentação de slides).
Para um tutorial sobre carrosséis, leia nosso Tutorial Bootstrap Carousel .
Observação: os carrosséis não são suportados corretamente no Internet Explorer 9 e versões anteriores (porque eles usam transições e animações CSS3 para obter o efeito de slide).
As classes de plug-in do carrossel
| Class | Description |
|---|---|
| .carousel | Creates a carousel |
| .slide | Adds a CSS transition and animation effect when sliding from one item to the next. Remove this class if you do not want this effect |
| .carousel-indicators | Adds indicators for the carousel. These are the little dots at the bottom of each slide (which indicates how many slides there are in the carousel, and which slide the user are currently viewing) |
| .carousel-inner | Adds slides to the carousel |
| .icon-next | Unicode icon (arrow pointing right), used in carousels. This is often used instead of a glyphicon |
| .icon-prev | Unicode icon (arrow pointing left), used in carousels. This is often used instead of a glyphicon |
| .item | Specifies the content of each slide |
| .left carousel-control | Adds a left button to the carousel, which allows the user to go back between the slides |
| .right carousel-control | Adds a right button to the carousel, which allows the user to go forward between the slides |
