some css that I've added:

background: url(../images/carousel1.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
background-size: cover;
}
.carousel-2 {
height: 100%;
background: url(../images/carousel2.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
background-size: cover;
}
but I can't figure out how I can this carousel with fading effect. I tried to change opacity from 1 to 0, when active item, but it makes 2 animations, it slides left and changes opacity too..
Can you help me?
This question is related to
twitter-bootstrap
The update from 3.2.x to 3.3.x broke some of the solutions explained here and on other threads because of the change: "Added transforms to improve carousel performance in modern browsers."
If you are using Bootstrap 3.3.x there's a solution here:
http://codepen.io/transportedman/pen/NPWRGq
Basically you need to add the "carousel-fade" class to your carousel so that you have:
<div class="carousel slide carousel-fade">
And then include the following CSS:
/*
Bootstrap Carousel Fade Transition (for Bootstrap 3.3.x)
CSS from: http://codepen.io/transportedman/pen/NPWRGq
and: http://stackoverflow.com/questions/18548731/bootstrap-3-carousel-fading-to-new-slide-instead-of-sliding-to-new-slide
Inspired from: http://codepen.io/Rowno/pen/Afykb
*/
.carousel-fade .carousel-inner .item {
opacity: 0;
transition-property: opacity;
}
.carousel-fade .carousel-inner .active {
opacity: 1;
}
.carousel-fade .carousel-inner .active.left,
.carousel-fade .carousel-inner .active.right {
left: 0;
opacity: 0;
z-index: 1;
}
.carousel-fade .carousel-inner .next.left,
.carousel-fade .carousel-inner .prev.right {
opacity: 1;
}
.carousel-fade .carousel-control {
z-index: 2;
}
/*
WHAT IS NEW IN 3.3: "Added transforms to improve carousel performance in modern browsers."
Need to override the 3.3 new styles for modern browsers & apply opacity
*/
@media all and (transform-3d), (-webkit-transform-3d) {
.carousel-fade .carousel-inner > .item.next,
.carousel-fade .carousel-inner > .item.active.right {
opacity: 0;
-webkit-transform: translate3d(0, 0, 0);
transform: translate3d(0, 0, 0);
}
.carousel-fade .carousel-inner > .item.prev,
.carousel-fade .carousel-inner > .item.active.left {
opacity: 0;
-webkit-transform: translate3d(0, 0, 0);
transform: translate3d(0, 0, 0);
}
.carousel-fade .carousel-inner > .item.next.left,
.carousel-fade .carousel-inner > .item.prev.right,
.carousel-fade .carousel-inner > .item.active {
opacity: 1;
-webkit-transform: translate3d(0, 0, 0);
transform: translate3d(0, 0, 0);
}
}
This can be accomplished using only CSS. To change the carousel to a fade transition instead of slide, use one of the following snippets (LESS or standard CSS).
LESS
// Fade transition for carousel items
.carousel {
.item {
left: 0 !important;
.transition(opacity .4s); //adjust timing here
}
.carousel-control {
background-image: none; // remove background gradients on controls
}
// Fade controls with items
.next.left,
.prev.right {
opacity: 1;
z-index: 1;
}
.active.left,
.active.right {
opacity: 0;
z-index: 2;
}
}
Plain CSS:
/* Fade transition for carousel items */
.carousel .item {
left: 0 !important;
-webkit-transition: opacity .4s; /*adjust timing here */
-moz-transition: opacity .4s;
-o-transition: opacity .4s;
transition: opacity .4s;
}
.carousel-control {
background-image: none !important; /* remove background gradients on controls */
}
/* Fade controls with items */
.next.left,
.prev.right {
opacity: 1;
z-index: 1;
}
.active.left,
.active.right {
opacity: 0;
z-index: 2;
}
Check this out : http://codepen.io/Rowno/pen/Afykb
.carousel-fade {
.carousel-inner {
.item {
opacity: 0;
transition-property: opacity;
}
.active {
opacity: 1;
}
.active.left,
.active.right {
left: 0;
opacity: 0;
z-index: 1;
}
.next.left,
.prev.right {
opacity: 1;
}
}
Works marvellously, I hope it works
Some good answers, but the problem with all solutions I have tried is that the images doesn´t fade into each other. Instead the first one fades completely out and than the next one fades in.
After a few hours of testing a found this sollution. Thx to http://www.1squarepear.com/adding-a-responsive-bootstrap-image-carousel-that-fades-instead-of-slides/
Add this in the css:
.carousel.fade {
opacity: 1;
}
.carousel.fade .item {
transition: opacity ease-out .7s;
left: 0;
opacity: 0; /* hide all slides */
top: 0;
position: absolute;
width: 100%;
display: block;
}
.carousel.fade .item:first-child {
top: auto;
opacity: 1; /* show first slide */
position: relative;
}
.carousel.fade .item.active {
opacity: 1;
}
I used the plain .css. It worked great. Note that I deleted the following from the bootstrap.min.css:
/* Fade transition for carousel items */
.carousel .item {
left: 0 !important;
-webkit-transition: opacity .4s;
/*adjust timing here */
-moz-transition: opacity .4s;
-o-transition: opacity .4s;
transition: opacity .4s;
}
.carousel-control {
background-image: none !important;
/* remove background gradients on controls */
}
/* Fade controls with items */
.next.left, .prev.right {
opacity: 1;
z-index: 1;
}
.active.left, .active.right {
opacity: 0;
z-index: 2;
}
for bootstrap 3, this is what i used
.carousel-fade .carousel-inner .item {
opacity: 0;
-webkit-transition-property: opacity;
-moz-transition-property: opacity;
-o-transition-property: opacity;
transition-property: opacity;
}
.carousel-fade .carousel-inner .active {
opacity: 1;
}
.carousel-fade .carousel-inner .active.left,
.carousel-fade .carousel-inner .active.right {
left: 0;
opacity: 0;
z-index: 1;
}
.carousel-fade .carousel-inner .next.left,
.carousel-fade .carousel-inner .prev.right {
opacity: 1;
}
.carousel-fade .carousel-control {
z-index: 2;
}
In reply to gerardnll's answer the Less code to extend Bootstrap 3.3.x carousel by fade effect:
//
// Carousel Fade effect
// --------------------------------------------------
// inspired from http://codepen.io/Rowno/pen/Afykb
.carousel-fade {
.carousel-inner {
.item {
.opacity(0);
.transition-property(opacity);
//.transition-duration(.8s);
}
.active {
.opacity(1);
&.left,
&.right {
left: 0;
.opacity(0);
z-index: 1;
}
}
.next.left,
.prev.right {
.opacity(1);
}
}
.carousel-control {
z-index: 2;
}
}
// WHAT IS NEW IN 3.3:
// "Added transforms to improve carousel performance in modern browsers."
// now override the 3.3 new styles for modern browsers & apply opacity
@media all and (transform-3d), (-webkit-transform-3d) {
.carousel-fade {
.carousel-inner {
> .item {
&.next,
&.prev,
&.active.right,
&.active.left {
.opacity(0);
.translate3d(0; 0; 0);
}
&.next.left,
&.prev.right,
&.active {
.opacity(1);
.translate3d(0; 0; 0);
}
}
}
}
}
The only thing is the transition duration which is not working as expected when longer than .8s (around). Maybe someone has a solution to solve this strange behaviour.
Note: The LESS code has .transition-duration(.8s);
commented, so the default carousel transition duration is used. You can play with the value and see the effect. Longer duration (> 0.8) renders the fade effect less smooth.
You can achieve a fade effect (instead of sticking with the default slide) using css only. Add these to your stylesheet
.carousel .item {
-webkit-transition: opacity 3s;
-moz-transition: opacity 3s;
-ms-transition: opacity 3s;
-o-transition: opacity 3s;
transition: opacity 3s;
}
.carousel .active.left {
left:0;opacity:0;z-index:2;
}
.carousel .next {
left:0;opacity:1;z-index:1;
}
you can use transition in css3:
.carousel-fade .carousel-inner .item {_x000D_
-webkit-transition-property: opacity;_x000D_
transition-property: opacity;_x000D_
}_x000D_
.carousel-fade .carousel-inner .item,_x000D_
.carousel-fade .carousel-inner .active.left,_x000D_
.carousel-fade .carousel-inner .active.right {_x000D_
opacity: 0;_x000D_
}_x000D_
.carousel-fade .carousel-inner .active,_x000D_
.carousel-fade .carousel-inner .next.left,_x000D_
.carousel-fade .carousel-inner .prev.right {_x000D_
opacity: 1;_x000D_
}_x000D_
.carousel-fade .carousel-inner .next,_x000D_
.carousel-fade .carousel-inner .prev,_x000D_
.carousel-fade .carousel-inner .active.left,_x000D_
.carousel-fade .carousel-inner .active.right {_x000D_
left: 0;_x000D_
-webkit-transform: translate3d(0, 0, 0);_x000D_
transform: translate3d(0, 0, 0);_x000D_
}_x000D_
.carousel-fade .carousel-control {_x000D_
z-index: 2;_x000D_
}
_x000D_
