| 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> |

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
}
]
