CDN

To start working with Slick right away, there's a couple of CDN choices availabile to serve the files as close, and fast as possible to your users:

Example using jsDelivr

Just add a link to the css file in your

:

<!-- Add the slick-theme.css if you want default styling --><link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/npm/[email protected]/slick/slick.css"><!-- Add the slick-theme.css if you want default styling --><link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/npm/[email protected]/slick/slick-theme.css">

Then, before your closing

tag add:

<script type="text/javascript" src="//cdn.jsdelivr.net/npm/[email protected]/slick/slick.min.js"></script>

Package Managers

# Bower bower install --save slick-carousel # NPM npm install slick-carousel

Data Attribute Settings

In slick 1.5 you can now add settings using the data-slick attribute. You still need to call $(element).slick() to initialize slick on the element.

Example:

### 1

### 2

### 3

### 4

### 5

### 6

Settings

Option | Type | Default | Description ------ | ---- | ------- | ----------- accessibility | boolean | true | Enables tabbing and arrow key navigation. Unless

slidesToShow

) after slide change. For full a11y compliance enable focusOnChange in addition to this. adaptiveHeight | boolean | false | Adapts slider height to the current slide appendArrows | string | $(element) | Change where the navigation arrows are attached (Selector, htmlString, Array, Element, jQuery object) appendDots | string | $(element) | Change where the navigation dots are attached (Selector, htmlString, Array, Element, jQuery object) arrows | boolean | true | Enable Next/Prev arrows asNavFor | string | $(element) | Enables syncing of multiple sliders autoplay | boolean | false | Enables auto play of slides autoplaySpeed | int | 3000 | Auto play change interval centerMode | boolean | false | Enables centered view with partial prev/next slides.

'ondemand' will load the image as soon as you slide to it, 'progressive' loads one image after the other when the page loads. mobileFirst | boolean | false | Responsive settings use mobile first calculation nextArrow | string (html | jQuery selector) | object (DOM node | jQuery object) |

<button type="button" class="slick-next">Next</button>

| Allows you to select a node or customize the HTML for the "Next" arrow. pauseOnDotsHover | boolean | false | Pauses autoplay when a dot is hovered pauseOnFocus | boolean | true | Pauses autoplay when slider is focussed pauseOnHover | boolean | true | Pauses autoplay on hover prevArrow | string (html | jQuery selector) | object (DOM node | jQuery object) |

<button type="button" class="slick-prev">Previous</button>

Can be 'window', 'slider' or 'min' (the smaller of the two). responsive | array | null | Array of objects containing breakpoints and settings objects (see example). Enables settings at given

breakpoint

. Set

settings

to "unslick" instead of an object to disable slick at a given breakpoint. rows | int | 1 | Setting this to more than 1 initializes grid mode. Use slidesPerRow to set how many slides should be in each row. rtl | boolean | false | Change the slider's direction to become right-to-left slide | string | '' | Slide element query slidesPerRow | int | 1 | With grid mode initialized via the rows option, this sets how many slides are in each grid row. slidesToScroll | int | 1 | # of slides to scroll at a time slidesToShow | int | 1 | # of slides to show at a time speed | int | 300 | Transition speed swipe | boolean | true | Enables touch swipe swipeToSlide | boolean | false | Swipe to slide irrespective of slidesToScroll touchMove | boolean | true | Enables slide moving with touch touchThreshold | int | 5 | To advance slides, the user must swipe a length of (1/touchThreshold) * the width of the slider. useCSS | boolean | true | Enable/Disable CSS Transitions useTransform | boolean | true | Enable/Disable CSS Transforms variableWidth | boolean | false | Disables automatic slide width calculation vertical | boolean | false | Vertical slide direction verticalSwiping | boolean | false | Changes swipe direction to vertical waitForAnimate | boolean | true | Ignores requests to advance the slide while animating zIndex | number | 1000 | Set the zIndex values for slides, useful for IE9 and lower

Responsive Option Example

The responsive option, and value, is quite unique and powerful. You can use it like so:

$(".slider").slick({ // normal options... infinite: false, // the magic responsive: [{ breakpoint: 1024, settings: { slidesToShow: 3, infinite: true } }, { breakpoint: 600, settings: { slidesToShow: 2, dots: true } }, { breakpoint: 300, settings: "unslick" // destroys slick }] });

Events

In slick 1.4, callback methods were deprecated and replaced with events. Use them before the initialization of slick as shown below:

// On swipe event $('.your-element').on('swipe', function(event, slick, direction){ console.log(direction); // left }); // On edge hit $('.your-element').on('edge', function(event, slick, direction){ console.log('edge was hit') }); // On before slide change $('.your-element').on('beforeChange', function(event, slick, currentSlide, nextSlide){ console.log(nextSlide); });

Event | Params | Description ------ | -------- | ----------- afterChange | event, slick, currentSlide | After slide change callback beforeChange | event, slick, currentSlide, nextSlide | Before slide change callback breakpoint | event, slick, breakpoint | Fires after a breakpoint is hit destroy | event, slick | When slider is destroyed, or unslicked. edge | event, slick, direction | Fires when an edge is overscrolled in non-infinite mode. init | event, slick | When Slick initializes for the first time callback. Note that this event should be defined before initializing the slider. reInit | event, slick | Every time Slick (re-)initializes callback setPosition | event, slick | Every time Slick recalculates position swipe | event, slick, direction | Fires after swipe/drag lazyLoaded | event, slick, image, imageSource | Fires after image loads lazily lazyLoadError | event, slick, image, imageSource | Fires after image fails to load

Methods

Methods are called on slick instances through the slick method itself in version 1.4, see below:

// Add a slide $('.your-element').slick('slickAdd',"

"); // Get the current slide var currentSlide = $('.your-element').slick('slickCurrentSlide');

This new syntax allows you to call any internal slick method as well:

// Manually refresh positioning of slick $('.your-element').slick('setPosition');
