Glider.js Initialization w/ full options:

1new Glider(document.querySelector('.glider'), {
2
3  // `auto` allows automatic responsive
4  // width calculations
5  slidesToShow: 'auto',
6  slidesToScroll: 'auto',
7
8  // should have been named `itemMinWidth`
9  // slides grow to fit the container viewport
10  // ignored unless `slidesToShow` is set to `auto`
11  itemWidth: undefined,
12
13  // if true, slides wont be resized to fit viewport
14  // requires `itemWidth` to be set
15  // * this may cause fractional slides
16  exactWidth: false,
17
18  // speed aggravator - higher is slower
19  duration: .5,
20
21  // dot container element or selector
22  dots: 'CSS Selector',
23
24  // arrow container elements or selector
25  arrows: {
26    prev: 'CSS Selector',
27    // may also pass element directly
28    next: document.querySelector('CSS Selector')
29  },
30
31  // allow mouse dragging
32  draggable: false,
33  // how much to scroll with each mouse delta
34  dragVelocity: 3.3,
35
36  // use any custom easing function
37  // compatible with most easing plugins
38  easing: function (x, t, b, c, d) {
39    return c*(t/=d)*t + b;
40  },
41
42  // event control
43  scrollPropagate: false,
44  eventPropagate: true,
45
46  // Force centering slide after scroll event
47  scrollLock: false,
48  // how long to wait after scroll event before locking
49  // if too low, it might interrupt normal scrolling
50  scrollLockDelay: 150,
51
52  // Force centering slide after resize event
53  resizeLock: true,
54
55  // Glider.js breakpoints are mobile-first
56  responsive: [
57    {
58      breakpoint: 900,
59      settings: {
60        slidesToShow: 2,
61        slidesToScroll: 2
62      }
63    },
64    {
65      breakpoint: 575,
66      settings: {
67        slidesToShow: 3,
68        slidesToScroll: 3
69      }
70    }
71  ]
72});

Change options:

1Glider(document.querySelector(element_path)).setOption({
2  name: value,
3  ...
4});
5
6// optionally call refresh
7Glider(document.querySelector(element_path)).refresh();

Bind event:

1document.querySelector(element_path).addEventListener('glider-slide-visible', function(event){
2  // `this` is bound to the glider element
3  // custom data located at `event.detail`
4  // access to Glider object via `Glider(this)`
5  ...
6});

Destroy with:

1Glider(document.querySelector(element_path)).destroy();

Browser support

Glider.js should run on all modern browsers. Support for older browser can be achieved by polyfilling document.classList, window.requestAnimationFrame, Object.assign and CustomEvent

Include glider-compat.min.js to load the aforementioned polyfills

Native Scrollbars

Most browsers now support the scrollbar-width property allowing us to avoid the messy hack below.

NOTE: This feature is marked as experimental and may not work in all browsers.

.glider-track {
  scrollbar-width: none;
}

Since Glider.js uses native scrolling, the browser wants to apply the standard scrollbar to the glider. In most cases, this is fine since the scrollbar can be hidden with CSS and Glider.js does so when appropriate. In browsers such as Firefox though, the scrollbars cannot be hidden with CSS and require additional markup to hide.

To hide the scrollbars in Firefox, you'll want to wrap your glider with <div class="glider-wrap"> and apply the following CSS/JS:

1@-moz-document url-prefix() {
2  .glider-track {
3    margin-bottom: 17px;
4  }
5  .glider-wrap {
6    overflow: hidden;
7  }
8}

1document.addEventListener('glider-loaded', hideFFScrollBars);
2document.addEventListener('glider-refresh', hideFFScrollBars);
3function hideFFScrollBars(e){
4  var scrollbarHeight = 17; // Currently 17, may change with updates
5  if(/firefox/i.test(navigator.userAgent)){
6    // We only need to appy to desktop. Firefox for mobile uses
7    // a different rendering engine (WebKit)
8    if (window.innerWidth > 575){
9      e.target.parentNode.style.height = (e.target.offsetHeight - scrollbarHeight) + 'px'
10    }
11  }
12}
