## Overview

Slick is a jQuery carousel/slider library. A page initializes it on slide elements with options; Slick builds and positions the carousel, responds to navigation and gestures, and supports responsive behavior, lazy image loading, accessibility, synchronized sliders, and lifecycle events. Runtime behavior is concentrated in `slick/slick.js`; styling is provided separately. The README documents capabilities whose individual implementations are not fully shown in the sampled source, so only documented, direct relationships are represented.

Main entry points: [`slick/slick.js`](https://github.com/kenwheeler/slick/blob/master/slick/slick.js) (Slick carousel), [`slick/slick.css`](https://github.com/kenwheeler/slick/blob/master/slick/slick.css) (Carousel styles), [`slick/slick-theme.css`](https://github.com/kenwheeler/slick/blob/master/slick/slick-theme.css) (Theme styles)
