A modern, light weight content slider
BoxSlider is a small library with zero dependencies that provides a light-weight, responsive content slider with various slide transition effects for modern browsers.
The library can be used standalone or by using the Web and React components.

Create the HTML structure for your content. Some effects require each slide to only contain an image but others support any form of content. See the documentation for the desired effect for detailed instructions.
<section id="content-box">
<!-- the content box -->

</section>To initialize the slider from JavaScript select the box and create a new BoxSlider instance with
the desired settings and effect.
import { BoxSlider, FadeSlider } from '@boxslider/slider'
const options = {
autoScroll: true,
timeout: 5000,
}
const box = document.querySelector('#content-box')
// Create a fading slide transition that moves to the next slide every 5 seconds (5000ms)
const slider = new BoxSlider(box, new FadeSlider(), options)
// Call API methods on the slider to manipulate it see documentation for available actions
slider.next().then(() => {
// Promise resolves when the box has transitioned to the next slide
})speed: number (default: 800)The time interval in milliseconds within which the slide animation will completeautoScroll: boolean (default: true)Set true to automatically transition through the slidestimeout: number (default: 5000)The time interval between slide transitions. For use with autoScrollpauseOnHover: boolean (default: false)Pause an auto-scrolling slider when the users mouse hovers over it. For use with autoScroll or a slider in play mode.swipe: boolean (default: true)Enable swiping the box to navigate to the next or previous slide.swipeTolerance: number (default 30)The number of pixels between the pointer down and pointer up events during the swipe action that will trigger the transition.
direction: 'horizontal' | 'vertical' (default: horizontal)The direction in which the cube should rotate to the next slide.perspective: number (default: 1000)The perspective to apply to the parent viewport element containing the box.
timingFunction: string (default: ease-in)The CSS transition timing function to use when fading slide opacity.
tileEffect: 'fade' | 'flip' (default: flip)The transition effect for animating the tiles during slide transitions.rows: number (default: 8)The number of tile rows into which the slide should be splitrowOffset: number (default: 50)The time offset for starting to animate the tiles in a row
timingFunction: string (default: ease-in-out)The CSS transition timing function to use when animating slides into position.cover: boolean (default: false)If true sets the slide effect to cover over the previous slide.
Shows a slide at the specified index starting from 0. Returns a promise that resolves when the transition is complete.
slider.skipTo(3).then(() => {
// show 4th slide
// transition complete
})Start auto scrolling the slides
slider.play()Pause an already auto scrolling slider
slider.pause()Destroys the slider and returns the HTML elements to their original state.
slider.destroy()Moves the slider to the next slide. Returns a promise that resolves when the transition is complete.
slider.next().then(() => {
// transition complete
})Moves the slider to the previous slide. Returns a promise that resolves when the transition is complete.
slider.prev().then(() => {
// transition complete
})Re-initialises the slider with updated options. An updated effect may also be passed as the second parameter.
slider.reset(options, effect)Adds a listener for the specified event. See the event documentation for the available events.
const afterTransitionListener = () => {
// Take some action when the event occurs
}
slider.addEventListener('after', afterTransitionListener)Removes the listener for the specified event.
slider.removeEventListener('after', afterTransitionListener)Fires before each slide transition starts. The current and next indexes are supplied in the event data as well as the transition speed.
slider.addEventListener('before', (data) => {
// data: {
// currentIndex: number
// nextIndex: number
// speed: number
// }
})Fires after each slide transition is complete. The active index is supplied in the event data
slider.addEventListener('after', (data) => {
// data: {
// currentIndex: number
// speed: number
// }
})Fires when the slider is put into play mode.
slider.addEventListener('play', (data) => {
// data: {
// currentIndex: number
// speed: number
// }
})Fires when an autoScroll'ing slider is paused.
slider.addEventListener('pause', (data) => {
// data: {
// currentIndex: number
// speed: number
// }
})Fires when a slider is destroyed.
slider.addEventListener('destroy', () => {
// No event data
})The slider will be applied with the aria-live="off" attribute when it is the autoScroll state and aria-live="polite"
when slide transitions are being controlled externally. Each slide is given the aria-roledescription="slide" attribute
but you will need to add aria-roledescription="carousel" to the container housing the slider and it's controls. An
example implementation is shown below.
<section class="carousel" aria-roledescription="carousel">
<div class="slider-controls">
<button id="prev-slide" aria-controls="demo-slider">Previous slide</button>
<button id="next-slide" aria-controls="demo-slider">Next slide</button>
<button id="play" aria-controls="demo-slider">Play</button>
</div>
<div class="slider" id="demo-slider">
<figure class="slide">
<picture>
<source srcset="happy-face-680.jpg" media="(min-width: 800px)" />
<img src="happy-face.jpg" alt="Young boy with a smile on his face" />
</picture>
</figure>
<figure class="slide">
<img src="sad-face.jpg" alt="Old lady with a sad look on her face" />
</figure>
<figure class="slide">

<script>
const slider = new BoxSlider(
document.getElementById('demo-slider'),
new CarouselSlider(),
{
autoScroll: false,
},
)
document
.getElementById('prev-slide')
.addEventListener('click', () => slider.prev())
// ... other button controls
