Can the Twitter Bootstrap Carousel plugin fade in and out on slide transition

Question

I have a very basic implementation of the Twitter Bootstrap Carousel plugin on a site that I am working on (http://furnitureroadshow.com/). I was just wondering if anyone h

Came across this issue when using Bootstrap 3. My solution was to add the carousel-fade class to the carousel main DIV and slot the following CSS in, somewhere after the Bootstrap CSS is included:

.carousel-fade .item {
  opacity: 0;
  -webkit-transition: opacity 2s ease-in-out;
  -moz-transition: opacity 2s ease-in-out;
  -ms-transition: opacity 2s ease-in-out;
  -o-transition: opacity 2s ease-in-out;
  transition: opacity 2s ease-in-out;
  left: 0 !important;
}

.carousel-fade .active {
  opacity: 1 !important;
}

.carousel-fade .left {
  opacity: 0 !important;
  -webkit-transition: opacity 0.5s ease-in-out !important;
  -moz-transition: opacity 0.5s ease-in-out !important;
  -ms-transition: opacity 0.5s ease-in-out !important;
  -o-transition: opacity 0.5s ease-in-out !important;
  transition: opacity 0.5s ease-in-out !important;
}

.carousel-fade .carousel-control {
  opacity: 1 !important;
}

The style transitions that Bootstrap applies mean that you have to have the mid-stride transitions (active left, next left) quickly, otherwise the item just ends up disappearing (hence the 1/2 second transition time).

I haven't experimented with adjusting the .item and .left transition times, but they will probably need adjusting proportionally to keep the effect looking nice.
