// Notes on the classes: // // 1. .carousel.pointer-event should ideally be pan-y (to allow for users to scroll vertically) // even when their scroll action started on a carousel, but for compatibility (with Firefox) // we're preventing all actions instead // 2. The .carousel-item-left and .carousel-item-right is used to indicate where // the active slide is heading. // 3. .active.carousel-item is the current slide. // 4. .active.carousel-item-left and .active.carousel-item-right is the current // slide in its in-transition state. Only one of these occurs at a time. // 5. .carousel-item-next.carousel-item-left and .carousel-item-prev.carousel-item-right // is the upcoming slide in transition. .carousel { position: relative; } .carousel.pointer-event { touch-action: pan-y; } .carousel-inner { position: relative; width: 100%; overflow: hidden; @include clearfix(); } .carousel-item { position: relative; display: none; float: left; width: 100%; margin-right: -100%; backface-visibility: hidden; @include transition($carousel-transition); } .carousel-item.active, .carousel-item-next, .carousel-item-prev { display: block; } .carousel-item-next:not(.carousel-item-left), .active.carousel-item-right { transform: translateX(100%); } .carousel-item-prev:not(.carousel-item-right), .active.carousel-item-left { transform: translateX(-100%); } // // Alternate transitions // .carousel-fade { .carousel-item { opacity: 0; transition-property: opacity; transform: none; } .carousel-item.active, .carousel-item-next.carousel-item-left, .carousel-item-prev.carousel-item-right { z-index: 1; opacity: 1; } .active.carousel-item-left, .active.carousel-item-right { z-index: 0; opacity: 0; @include transition(0s $carousel-transition-duration opacity); } } // // Left/right controls for nav // .carousel-control-prev, .carousel-control-next { position: absolute; top: 0; bottom: 0; z-index: 1; // Use flex for alignment (1-3) display: flex; // 1. allow flex styles align-items: center; // 2. vertically center contents justify-content: center; // 3. horizontally center contents width: $carousel-control-width; color: $carousel-control-color; text-align: center; opacity: $carousel-control-opacity; @include transition($carousel-control-transition); // Hover/focus state @include hover-focus { color: $carousel-control-color; text-decoration: none; outline: 0; opacity: $carousel-control-hover-opacity; } } .carousel-control-prev { left: 0; @if $enable-gradients { background: linear-gradient(90deg, rgba($black, .25), rgba($black, .001)); } } .carousel-control-next { right: 0; @if $enable-gradients { background: linear-gradient(270deg, rgba($black, .25), rgba($black, .001)); } } // Icons for within .carousel-control-prev-icon, .carousel-control-next-icon { display: inline-block; width: $carousel-control-icon-width; height: $carousel-control-icon-width; background: no-repeat 50% / 100% 100%; } .carousel-control-prev-icon { background-image: $carousel-control-prev-icon-bg; } .carousel-control-next-icon { background-image: $carousel-control-next-icon-bg; } // Optional indicator pips // // Add an ordered list with the following class and add a list item for each // slide your carousel holds. .carousel-indicators { position: absolute; right: 0; bottom: 0; left: 0; z-index: 15; display: flex; justify-content: center; padding-left: 0; // override
