Twitter Bootstrap Carousel Crossfade
Use the following LESS snippet in your site styles to override the default slide behavior of Bootstrap's carousel to create a crossfade. I've seen other examples on SO for doing this, but all of them had issues either with updated Bootstrap versions or with components like calling .slider(index) to "slide" to a specific item.
.carousel {
.item {
.transition(.7s ease-in-out opacity);
left: 0 !important;
}
.next.left, .prev.right {
opacity: 1;
z-index: 1;
}
.active.left, .active.right {
opacity: 0;
z-index: 2;
}
}You can see this in action on https://us.pycon.org/2013/ in the sponsor carousel.

How does this translate into non .less CSS?
This just worked for me:
carousel .item {
display: none;
position: relative;
-webkit-transition:.7s ease-in-out opacity;
-moz-transition: .7s ease-in-out opacity;
-ms-transition: .7s ease-in-out opacity;
-o-transition: .7s ease-in-out opacity;
transition: .7s ease-in-out opacity;
left: 0 !important;
transition: 0.6s ease-in-out left; */
}
.carousel .next.left,
.carousel .prev.right {
opacity: 1;
z-index: 1;
}
.carousel .active.left {
opacity: 0;
z-index: 2;
}
.carousel .active.right {
opacity: 0;
z-index: 2;
}
you can see the results here:
Thanks to you guys, I now have this (most simply):
.carousel .item {
-webkit-transition: .7s ease-in-out opacity;
-moz-transition: .7s ease-in-out opacity;
-ms-transition: .7s ease-in-out opacity;
-o-transition: .7s ease-in-out opacity;
transition: .7s ease-in-out opacity;
left: 0 !important;
}
.carousel .active.left,
.carousel .active.right {
opacity: 0;
z-index: 2;
}
/--- ...and only if you're using the prev/next buttons ---/
.carousel .next.left,
.carousel .prev.right {
opacity: 1;
z-index: 1;
}
I added this to keep the navigation buttons from flashing during the crossfade:
.carousel-control {
z-index:3;
}
Beautiful! Thanks so much. It works great.
Thanks Luke! Works perfectly in Safari, but not Chrome or FF for me. Is it working for others?
