#### Demo

#### 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:
- https://cdnjs.com/libraries/slick-carousel
- https://www.jsdelivr.com/projects/jquery.slick
#####Example using jsDelivr
Just add a link to the css file in your `<head>`:
```html
<link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/jquery.slick/1.6.0/slick.css"/>
<!-- Add the slick-theme.css if you want default styling -->
<link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/jquery.slick/1.6.0/slick-theme.css"/>
```
Then, before your closing ```<body>``` tag add:
```html
<script type="text/javascript" src="//cdn.jsdelivr.net/jquery.slick/1.6.0/slick.min.js"></script>
```
#### Package Managers
```sh
# 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:
```html
<div data-slick='{"slidesToShow": 4, "slidesToScroll": 4}'>
<div><h3>1</h3></div>
<div><h3>2</h3></div>
<div><h3>3</h3></div>
<div><h3>4</h3></div>
<div><h3>5</h3></div>
<div><h3>6</h3></div>
</div>
```

responsive | array | null | Array of objects [containing breakpoints and settings objects (see example)](#responsive-option-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.

##### Responsive Option Example
The responsive option, and value, is quite unique and powerful.
You can use it like so:
```javascript
$(".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:
```javascript
// 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:
```javascript
// Add a slide
$('.your-element').slick('slickAdd',"<div></div>");
// Get the current slide
var currentSlide = $('.your-element').slick('slickCurrentSlide');
```
This new syntax allows you to call any internal slick method as well:
```javascript
// Manually refresh positioning of slick
$('.your-element').slick('setPosition');
```
Method | Argument | Description

`slick` | options : object | Initializes Slick
`unslick` | | Destroys Slick

`slickAdd` | element : html or DOM object, index: int, addBefore: bool | Add a slide. If an index is provided, will add at that index, or before if addBefore is set. If no index is provided, add to the end or to the beginning if addBefore is set. Accepts HTML String || Object
`slickRemove` | index: int, removeBefore: bool | Remove slide by index. If removeBefore is set true, remove slide preceding index, or the first slide if no index is specified. If removeBefore is set to false, remove the slide following index, or the last slide if no index is set.
`slickFilter` | filter : selector or function | Filters slides using jQuery .filter syntax
`slickUnfilter` | | Removes applied filter

Initialize with:
```javascript
$(element).slick({
dots: true,
speed: 500
});
```
Change the speed with:
```javascript
