Introduction
Swiffy slider is a wrapper defined in html with slides, navigation and indicators as its children.
All options and behavior is controlled with css classes that is added to the wrapper. No js configuration.
The wrapper is the .swiffy-slider
element - options to control layout and behavior of slides, navigation and indicators are added to this element.
Markup structure
The slider markup is a .swiffy-slider
wrapper that has 3 sections.
- One
.slider-container
that contains the slides - Two
.slider-nav
buttons that is navigation buttons previous and next (optional) - One
.slider-indicators
that contains the indicators (optional)
<div class="swiffy-slider [slider options] [navigation options] [indicator options]" data-slider-nav-autoplay-interval="3000">
<ul class="slider-container">
<li>Slide 1</li>
<li>Slide 2</li>
</ul>
<button type="button" class="slider-nav"></button>
<button type="button" class="slider-nav slider-nav-next"></button>
<div class="slider-indicators">
<button class="active"></button>
<button></button>
</div>
</div>
This example uses ul>li for slides. Can also be i.e. div or other elements. This example uses button for navigation. Could also be divs, but cannot be ul>li as that would be nested. This example uses div>button for indicators but could be other elements, i.e. ul>li structure instead. Wether to use buttons or div for the navigating elements, depends on how WCAG needs to be handled.
Slider options (CSS Classes)
Options are the css classes that can be added to the .swiffy-slider
element to control how the slider will look and behave. No config in JS or similar.
The example below use the .slider-item-show2
option to show 2 slides and .slider-item-reveal
to reveal part of the next and previous slide. By adding additional classes behavior and layout is controlled.
Head over to the configurator to try all options
<div class="swiffy-slider slider-item-show2 slider-item-reveal">
<ul class="slider-container">
<li>Slide 1</li>
<li>Slide 2</li>
<li>Slide 3</li>
</ul>
</div>

slider-item-ratio |
Enables ratio sizing of the slide elements. Default ratio is 2:1 or 50% meaning the slides have half the heigh of their width. This option sets object-fit:cover; on first element inside the slide element - to stretch images to fill out the slide box and keep aspect ratio. |
slider-item-ratio-32x9 slider-item-ratio-21x9 slider-item-ratio-2x1 slider-item-ratio-16x9 slider-item-ratio-4x3 slider-item-ratio-1x1 slider-item-ratio-3x4 |

slider-item-snapstart |
Snaps slides to start of the slider wrapper instead of center when using .slider-item-reveal |

slider-nav-nodelay |
Disables smooth scrolling when sliding using navigation buttons, indicators and autoplay. Makes the new slide or page appear instantly with no scroll smoothing. Does not affect touch navigation |
slider-nav-autoplay |
Automatically slide to next slide or next page in intervals. Default is 2500 ms = 2.5s |

slider-nav-outside |
Moves the navigation buttons outside the slider wrapper and shrinks the width of the slider wrapper accordingly (by 3 or 5 rem on each side depending on navigation style) |
slider-nav-outside-expand |
Moves the navigation buttons outside the slider wrapper by applying negative margins (-3 or -5 rem) so the slides and wrapper keeps their size. The navigation buttons overlays surrounding content. |
slider-nav-scrollbar |
Makes the scrollbar for the .slider-container visible. Acts as indicator and navigation if running in css only mode. On touch devices the scrollbar is not shown when not sliding because that is how the browser behaves |

All options and behavior is handled by the css classes, so using the scripts directly is only for more advanced scenarios.
Method _______________________________ |
Description _______________________________ |
---|---|
swiffyslider.version; |
Needs no explanation :-) |
swiffyslider.init(rootElement = document.body); |
Initializes all instances of .swiffy-slider elements and binds events to handle navigation, indicators and autoplay. By default document.body is searched for instances, but can be limited further to i.e. content area (and skip header, navigation, footer etc) to further improve init performance. |
swiffyslider.initSlider(sliderElement); |
Initializes one instance of swiffy slider wrapper. The passed element has to be a .swiffy-slider element |
swiffyslider.slide(sliderElement, next = true); |
Slides to the next slide or next page depending on the nav settings. The passed slider element has to be a .swiffy-slider element. By default this method slides next, but call it with false to slide to previous |
swiffyslider.slideToByIndicator(); |
This method is called when an indicator button is clicked. Should not be called directly. Instead call slideTo |
swiffyslider.slideTo(sliderElement, slideIndex); |
Slides to the specified slide (index starts with 0 for first slide). The passed slider element has to be a .swiffy-slider element. |
swiffyslider.onSlideEnd(sliderElement, delegate, timeout = 125); |
Provide a callback/delegate function to get called when sliding ends. The default timeout is 125ms and should not be too low as it could cause the delegate to be called more than once on each scroll. The passed slider element has to be a .swiffy-slider element. |
swiffyslider.autoPlay(sliderElement, timeout, autopause); |
Manually starts autoplay for a container using the specified timeout. Autopause can be enabled. Usually auto play is handled using css option classes. This method can be used to start autoplay when the slider scrolls into view or similar. The passed slider element has to be a .swiffy-slider element. |
swiffyslider.handleIndicators(sliderElement); |
Manually updates the indicators active state to reflect the current position of the slider. The passed slider element has to be a .swiffy-slider element. |
Listening for sliding ends for a container
<script>
const sliderElement = document.getElementById('myslider');
swiffyslider.onSlideEnd(sliderElement, function() {
console.log('Scrolling stopped');
});
</script>
Listening for sliding ends for a container and find visible slides
<script>
window.addEventListener('load', () => {
const sliderElement = document.getElementById('myslider');
swiffyslider.onSlideEnd(sliderElement, function() {
const visibleSlideElements = getVisibleSlides(sliderElement);
const visible = [];
for (const slide of visibleSlideElements) {
visible.push(slide.innerText);
}
console.log(visible);
console.log(visibleSlideElements);
});
});
function getVisibleSlides(sliderElement) {
const container = sliderElement.querySelector('.slider-container');
//returns an array of slide elements that are fully or partially visible
const visibleSlides = [];
//We are using a grid layout and the slides left and right properties include the width of the gap, so when comparing with container width add a gap for each side of the slide gap.
const gapWidth = parseInt(window.getComputedStyle(container).columnGap);
for (const slide of container.children) {
var slideScrollLeftPosition = slide.getBoundingClientRect().left - container.getBoundingClientRect().left;
var slideScrollRightPosition = slideScrollLeftPosition + slide.offsetWidth - gapWidth;
if (slideScrollLeftPosition >= 0 && slideScrollRightPosition <= container.offsetWidth) {
visibleSlides.push(slide);
}
}
return visibleSlides;
}
</script>
Javascript loading and binding
Avoid autobinding by adding data-noinit
attribute on the script tag and then attach the slider manually
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/swiffy-slider.min.js" data-noinit defer>
<script>
window.addEventListener('load', () => {
//Use only one of the loading options below!
//loads all sliders
swiffyslider.init();
//loads specific slider
swiffyslider.initSlider(document.getElementById('myslider'));
});
</script>
<div class="swiffy-slider" id="myslider">
<div class="slider-container">
<div></div>
</div>
...
</div>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/swiffy-slider.min.js" data-noinit defer>
<script>
window.addEventListener('load', () => {
//loads all sliders in main and skip header and footer search for increased init performance.
swiffyslider.init(document.getElementById('content'));
});
</script>
<header>...</header>
<main id="content">
<div class="swiffy-slider" id="myslider">
<div class="slider-container">
<div></div>
</div>
...
</div>
</main>
<footer>...</footer>
Load as module using ES version of the script
<script type="module">
import {swiffyslider} from 'https://cdn.jsdelivr.net/npm/[email protected]/dist/js/swiffy-slider.ESM.min.js';
window.swiffyslider = swiffyslider;
window.swiffyslider.init();
</script>
Load as ES module on demand, here using load - could be when slider scrolls into view or navigation arrow is clicked the first time. Load module and initialize sliders.
<script>
window.addEventListener("load", () => {
import ('https://cdn.jsdelivr.net/npm/[email protected]/dist/js/swiffy-slider.ESM.min.js').then((swiffysliderModule) => {
swiffysliderModule.swiffyslider.init();
});
});
</script>
Load as ES module on demand. Load module and assign to window for later script manipulation of slides
<script>
window.addEventListener("load", () => {
import ('https://cdn.jsdelivr.net/npm/[email protected]/dist/js/swiffy-slider.ESM.min.js').then((swiffysliderModule) => {
window.swiffyslider = swiffysliderModule.swiffyslider;
window.swiffyslider.init();
});
});
</script>
CSS variables
The Swiffy Slider CSS is making use of a number of CSS variables that can be overriden to control behavior and styling
Slide sizes, ratios, navigation etc. can be controlled by overruling the variable on the .swiffy-slider
instance or in custom css.
Variable | Example | Description |
---|---|---|
--swiffy-slider-item-width |
--swiffy-slider-item-width:75%; |
Calculated based on the number of slides shown, the gap, reveal etc. Should not be overriden. INFO If needed, it has to be overriden on the .slider-container element. |
--swiffy-slider-item-gap |
--swiffy-slider-item-gap:25px; |
Changes the gap between slides when enabled. Default --swiffy-slider-item-gap is 1rem, but can be any valid CSS mesurement. The --swiffy-slider-item-gap is part of the calculation of --swiffy-slider-item-width |
--swiffy-slider-item-reveal |
--swiffy-slider-item-reveal:20%; |
Changes the width of the reveal of next and previous slides when enabled. Default --swiffy-slider-item-reveal is 8rem if previous and next is revealed and 4rem if only next is revealed (if .slider-item-snapstart is in use). The --swiffy-slider-item-reveal is part of the calculation of --swiffy-slider-item-width |
--swiffy-slider-item-ratio |
--swiffy-slider-item-ratio:100/33.3 |
Sets the ratio to a custom value. Use with .slider-item-ratio and omit use of any .slider-item-ratio-* classes |
--swiffy-slider-item-count |
--swiffy-slider-item-count:8; |
Sets the number of slides to show - same as using .slider-item-show{n} but can i.e. be set to a number higher than 6 if needed. |
--swiffy-slider-nav-light |
--swiffy-slider-nav-light:lightcyan; |
Sets the light color for navigation arrows. Default is #fff . Use to control the color of light navigation. Square and Round navigation use both colors - one for backgrond, the other for arrow color. |
--swiffy-slider-nav-dark |
--swiffy-slider-nav-dark:darkolivegreen; |
Sets the dark color for navigation arrows. Default is #333 . Use to control the color of dark navigation. Square and Round navigation use both colors - one for backgrond, the other for arrow color. Can be any color variable. |
--swiffy-slider-nav-zoom |
--swiffy-slider-nav-zoom:1.25; |
Use to overrule the navigation arrow sizes. Default is 1 for normal sizes and .75 for small sized navigation. Set to i.e. 1.25 to make navigation arrows larger. |
--swiffy-slider-track-opacity |

Safari smooth scrolling polyfill
Sliding the carousel on touch devices using fingers are not affected by this issue.
When sliding using buttons, indicators and javascript, the new slides are shown instantly with no smoothing when using Safari.
In Safari based browsers, smooth scrolling is not supported because it is still lacking browser support. See Can I use
If you want to support smoooth scrolling on Safari based browsers, add this polyfill to your head section
<script src="https://unpkg.com/smoothscroll-polyfill/dist/smoothscroll.min.js"></script>
Limitations
These limitations are known and intentionally there to keep this library small, fast and smooth.
- Scroll speed comes in 2 flavors - instant or 'smooth'. This is because that is what browsers support out of the box using CSS scroll-behavior. See MDN
- Does not support slides of uneven widths. The width is controlled by the width of the wrapper and can have 1-6 slides per page depending on configuration.
- Smooth scrolling is not supported out of the box in Safari (iOS + Mac) but can be fixed using a polyfill. See polyfill
- RTL is untested but as the entire slider is just markup, it should be supported very well
- Works in 'modern' browsers from the last ~3 years only. No IE support or anything funny.
Use other sliders and carousels if these limitations is important in your project.
Contributing
You are more than welcome to contribute by opening issues and create pull requests. Keep in mind that this project is meant to be very simple in nature and support recent browsers only.
This project is not going into a race of adding as many features as possible - but quite the opposite. Performance and filesize has high priority.
The general rule is, that Swiffy Slider is covering the most common usages, and that more exotic usages are made in examples. If not at least 50% of all installations need a feature, the feature probably belong somewhere else.
Examples of more exotic use cases are more than welcome as part of the examples, so please create pulls for that.
Open tasks that you could help with:
- Svelte component
- Vue component
- React component
Thank you for your understanding.

Two clicks to jump from the last slide to the first when "Mouse draggable" is active
Hi,
when "Mouse draggable" is set, the last slide switches to the first slide after repeated mouse click only. The first click on the right arrow makes the slide twitch a bit, and it switches only after the second click.
Tested on the latest FF, Chrome, and Chrome Canary.
You can check it on the first example from the Configurator with these settings.
Unfortunately, it isn't reproduced all the time on the configurator page, but I have this issue 100% of the time on my test page. I can email it to you if that's ok.
Differents height for images
Is your feature request related to a problem? Please describe. For a web application, we let users upload images, but we end up with images of different sizes
Describe the solution you'd like It is possible to have a height that changes according to the size of the images rather than the size of the images ?
Additional context At the end of this slider, there is an example of Autoheight
I like your slider, very easy to use :)
No loop in Chromium with zoom/scaling
The loop stops working when the browser is zoomed out or in (and with some zoom levels it still loops) or when OS is set up to interface scaling. Maybe it has something to do with
grid-auto-columns
.Applies to at least Chrome, Edge.
Autoplay don't work on mobile
Describe the bug The slider work fine on desktop and on the adaptative view on desktop, but on my mobile the autoplay don't work, i see only the first image. (scroll works)
Smartphone (please complete the following information):
Additional context www.eliot.fr
Script skips images
Describe the bug On a 5 image-slider, the script skips 2 and 4. You can see that the button list below is visited only on 1, 3 and 5. Why?
The code is as follows:
<div id="employees" class="swiffy-slider slider-nav-outside slider-nav-visible slider-nav-nodelay slider-nav-autoplay slider-nav-autopause slider-item-show1 slider-indicators-outside slider-nav-animation slider-nav-animation-fadein slider-nav-animation-slow slider-item-last-visible" data-slider-nav-autoplay-interval="5000"> <ul class="slider-container"> <li class="employee"> <img src="https://info.spiria.com/hubfs/Erika.png" alt="Erika"> <div> <div id="hs_cos_wrapper_module_165049619677012_" class="hs_cos_wrapper hs_cos_wrapper_widget hs_cos_wrapper_type_inline_text" style="" data-hs-cos-general-type="widget" data-hs-cos-type="inline_text" data-hs-cos-field="employee_title"></div><br>Erika </div> </li> [...] </ul> <button type="button" class="slider-nav"></button> <button type="button" class="slider-nav slider-nav-next"></button> <div class="slider-indicators"> <button class=""></button> <button></button> <button class=""></button> <button></button> <button class="active"></button> </div> </div>
The script is fired this way:
window.addEventListener('load', () => { swiffyslider.initSlider(document.getElementById('employees')); });
Standard Sass and CSS import doesn't seem to be working?
Hi, I couldn't find documentation on how to import the CSS files outside of JS. I see there's another similar issue over here: https://github.com/dynamicweb/swiffy-slider/issues/24 (I'm currently using version
1.5.1
, which should have fixed that).Currently, doing
@import "swiffy-slider";
or@import swiffy-slider/dist/css/swiffy-slider;
causes a whole lot of problems with Vite.js (which uses esbuild under the hood). For instance:PS.: This might not have anything to do with it, but after looking at other packages, I notice that

.[Feature Request] Ken burns / zoom slide effect when showing
Please add the ability to make the slides zoom while displaying Example I found on codepen: https://codepen.io/ibanez182/pen/LZPgrY
Also for ADA/WCAG, please allow a pause button option
Otherwise this slider is the best modern slider! Thank you
automatic and responsive indicators
Is your feature request related to a problem? Please describe. could not find any solution where indicators are automatically and responsively generated according number of slides
Describe the solution you'd like calculate number of "pages" and insert the same amount of indicators to DOM accordingly
Describe alternatives you've considered none :)
Additional context currently it's hardcoded and thus not responsive

If "Mouse draggable" is set, swiping on mobile does not work
Currently if "Mouse draggable" is set, it is not possible on mobile phones to drag the slider. I think is a problem and UX could be improved
Describe the solution you'd like For a better/expected UX it should still be possible to swipe on smartphones even if the setting "Mouse draggable" is set.
Thank you!

Remove html template tag from children
The problem solved with this PR is about the tag "template" who is parsed as an slide or an indicator when the library init the slider.
See issue https://github.com/dynamicweb/swiffy-slider/issues/46
Remove "template" tag from children of .slider-container and .slider-indicators making library compatible with AlpineJS
Is your feature request related to a problem? Please describe. I want the library to be compatible with AlpineJs and the Web HTML Element "template". AlpineJS use the "template" element for every actions, loop etc... and SwiffySlider take alld child element to display indicators and slide. See AlpineJS Templating usage : https://alpinejs.dev/essentials/templating#looping-elements
Describe the solution you'd like I already implemented the solution (PR in preparation) it simply consist in excluding the "template" from the children and let all other tags as is

Bare bones version?
Is there the possibility to make a "bare bones" version of Swiffy Slider? Or does that not fit into the concept?
I have replaced a couple of old sliders on clients' websites with Swiffy Slider, and for the new slider to fit into the whole design, I had to override quite a bit of the CSS.
I do love the possibility to style the slider just by adding classes, and I am not overly bothered by loading CSS I don't end up using. But it would be great to have a .pure class (or something) that does not style the elements, so I only have to add, not to override.
As I have said before – your slider is a dream come true when I had already given up on looking for something usable and also on trying to write my own. Many, many thanks for this great piece of software – and no less for the stellar support!
