I see you can set the interval but I want to control how fast the items slide?
// Sets interval...what is transition slide speed?
$('#mainCarousel').carousel({
interval: 3000
});
This question is related to
twitter-bootstrap
All carousel
<script type="text/javascript">
$(document).ready(function () {
$('.carousel').carousel({
interval: 15000
})
});
</script>
If using the ngCarousel module, edit the interval variable in the file @ng-bootstrap/ng-bootstrap/carousel-config.js like so:
var NgbCarouselConfig = /** @class */ (function () {
function NgbCarouselConfig() {
this.interval = 10000;
this.wrap = true;
...
}
...
What worked for me was to change interval in bootstrap.js
Carousel.DEFAULTS = {
interval: 2000, // <----- change this
pause: 'hover',
wrap: true,
keyboard: true
}
To complement the previous answers, after you edit your CSS file, you just need to edit CAROUSEL.TRANSITION_DURATION
(in bootstrap.js) or c.TRANSITION_DURATION
(if you use bootstrap.min.js) and to change the value inside it (600 for default). The final value must be the same that you put in your CSS file (for example, 10s in CSS = 10000 in .js)
Carousel.VERSION = '3.3.2'
Carousel.TRANSITION_DURATION = xxxxx /* Your number here*/
Carousel.DEFAULTS = {
interval: 5000 /* you could change this value too, but to add data-interval="xxxx" to your html it's fine too*/
pause: 'hover',
wrap: true,
keyboard: true
}
Add Data interval
data-interval="20000"
If you need to do it programmatically to change (for example) the speed based on certain conditions on perhaps only one of many carousels, you could do something like this:
If the Html is like this:
<div id="theSlidesList" class="carousel-inner" role="listbox">
<div id="Slide_00" class="item active"> ...
<div id="Slide_01" class="item"> ...
...
</div>
JavaScript would be like this:
$( "#theSlidesList" ).find( ".item" ).css( "-webkit-transition", "transform 1.9s ease-in-out 0s" ).css( "transition", "transform 1.9s ease-in-out 0s" )
Add more .css( ... ) to include other browsers.
For bootstrap 4 with scss, you can overwrite the configuration variable $carousel-transition-duration
in your _variables.scss
like this:
$carousel-transition-duration: 2s;
Or for element individual duration set the
.carousel-item {
transition-duration: 2s;
}
of your specific element in your css/scss.
In your main.js file or bootstrap.js, change the value of autoplayTimeout
$('.carousel').each(function () {
$(this).owlCarousel({
nav: $(this).data('nav'),
dots: $(this).data('dots'),
loop: $(this).data('loop'),
margin: $(this).data('space'),
center: $(this).data('center'),
dotsSpeed: $(this).data('speed'),
autoplay: $(this).data('autoplay'),
transitionStyle: $(this).data('transition'),
animateOut: $(this).data('animate-out'),
animateIn: $(this).data('animate-in'),
autoplayTimeout: 3000,
responsive: {
0: {
items: 1,
},
400: {
items: $(this).data('slide-sm'),
},
700: {
items: $(this).data('slide-md'),
},
1000: {
items: $(this).data('slide'),
}
}
});
});
_x000D_
In your CSS:
.carousel-item {
transition-duration: 1.5s, 1.5s;
}
Take care, the time is included in data-interval defined for the carousel.
Hope it helps... :)
With Bootstrap 4, just use this CSS:
.carousel .carousel-item {
transition-duration: 3s;
}
Change 3s
to the duration of your choice.
Just write data-interval
in the div
containing the carousel:
<div id="myCarousel" class="carousel slide" data-ride="carousel" data-interval="500">
Example taken from w3schools.
For Twitter Bootstrap 3:
You must change the CSS transition as specified in the other answer:
.carousel-inner > .item {
position: relative;
display: none;
-webkit-transition: 0.6s ease-in-out left;
-moz-transition: 0.6s ease-in-out left;
-o-transition: 0.6s ease-in-out left;
transition: 0.6s ease-in-out left;
}
From 0.6 seconds to 1.5 seconds (for example).
But also, there is some Javascript to change. In the bootstrap.js there is a line:
.emulateTransitionEnd(600)
This should be changed to the corresponding amount of milliseconds. So for 1.5 seconds you would change the number to 1500:
.emulateTransitionEnd(1500)
after including bootstrap.min.js
or uncompressed one, you can just add interval as a parameter as below
jQuery("#numbers").carousel({'interval':900 });
It works for me
If you don't want to change the js files of bootstrap, you can also directly inject the wanted value into the jquery plugin (bootsrap 3.3.6).
This requires of course, that the carousel is activated manually via js, not directly via the data-ride attribute.
For example:
var interval = 3500;
$.fn.carousel.Constructor.TRANSITION_DURATION = interval - 500;
elem.carousel({
interval : interval
});
You need to set interval in the main DIV as data-interval tag. The it will work fine and you can give different time to different slides.
<div class="carousel" data-interval="5000">
for me worked to add this at the end of my view:
<script type="text/javascript">
$(document).ready(function(){
$("#myCarousel").carousel({
interval : 8000,
pause: false
});
});
</script>
it gives to the carousel an interval of 8 seconds
no need any external code just use data-interval=""
attribute
more information visit getbootstrap
<div id="carouselExampleCaptions" class="carousel slide" data-ride="carousel" data-interval="2500">
when you want change speed change "2500"
You can use this
<div id="carouselExampleSlidesOnly" class="carousel slide" data-ride="carousel" data-interval="4000">
Just add data-interval="1000"
where next picture will be after 1 sec.
If you are looking to edit the speed in which the slides come in and out (not the time in between changing slides called interval) for bootstrap 3.3.5 | After loading CDN bootstrap styles, overwrite the styles in your own css styleseet using the following classes. the 1.5 is the time change.
.carousel-inner > .item {
-webkit-transition: 1.5s ease-in-out ;
-o-transition: 1.5s ease-in-out ;
transition: 1.5s ease-in-out ;
}
.carousel-inner > .item {
-webkit-transition: -webkit-transform 1.5s ease-in-out;
-o-transition: -o-transform 1.5s ease-in-out;
transition: transform 1.5s ease-in-out;
}
after that, you will need to replace the carousel function in javascript. To do this you will overwrite the default bootstrap.min.js function after it loads. (In my opinion it is not a good idea to overwrite bootstrap files directly). so create a mynewscript.js and load it after bootstrap.min.js and add the new carousel function. The only line you will want to edit is this one, Carousel.TRANSITION_DURATION = 1500. 1500 being 1.5. Hope this helps.

One thing I noticed is that Bootstrap 3 is adding the styles with both a .6s
and 0.6s
. So you may need to explicitly define your transition duration like this (CSS)
.carousel-inner>.item {
-webkit-transition: 0.9s ease-in-out left;
transition: 0.9s ease-in-out left;
-webkit-transition: 0.9s, ease-in-out, left;
-moz-transition: .9s, ease-in-out, left;
-o-transition: .9s, ease-in-out, left;
transition: .9s, ease-in-out, left;
}
