Tiny Slider 2


Tiny slider for all purposes, inspired by Owl Carousel.


Test results

Previous versions: v1, v0

Warning: tiny-slider works with static content and it works in the browser only. If the HTML is loaded dynamically, make sure to call tns() after its loading.


What's new

  • Using % instead of px (No more recalculation of each slide width on window resize)
  • Using CSS Mediaqueries if supported
  • Save browser capability values to localStorage, so they will not be recheck again until browser get upgraded or user clear the localStorage manually.
  • More options available for responsive. (Start from v2.1.0, issue 53)
  • Insert controls and nav before slider instead of after (issue 4)
  • Move autoplay button out of nav container. (Start from v2.1.0)
  • Some selector changes in tiny-slider.scss

Migrating to v2

  • Update controls and / or nav styles based on their position changes.
  • Update the slider selectors accordingly if used in your CSS or JS.
  • Update styles related to autoplay button.

Responsive options

The following options can be redefined in responsive field: startIndex, items, slideBy, speed, autoHeight, fixedWidth, edgePadding, gutter, center, controls, controlsText, nav, autoplay, autoplayHoverPause, autoplayResetOnVisibility, autoplayText, autoplayTimeout, touch, mouseDrag, arrowKeys, disable

  var slider = tns({
    container: '.my-slider',
    items: 1,
    responsive: {
      640: {
        edgePadding: 20,
        gutter: 20,
        items: 2
      700: {
        gutter: 30
      900: {
        items: 3


  • The breakpoints behave like (min-width: breakpoint) in CSS, so an undefined option will be inherited from previous small breakpoints.
  • fixedWidth can only be changed to other positive integers. It can't be changed to negative integer, 0 or other data type. top↑


The slider returns a slider object with some properties and methods once it's initialized:

  version: version, // tiny-slider version
  getInfo: info(),
  events: events, // Object
  goTo: goTo(),
  play: play(),
  pause: pause(),
  isOn: isOn, // Boolean
  updateSliderHeight: updateInnerWrapperHeight(),
  refresh: initSliderTransform(),
  destroy: destroy(),
  rebuild: rebuild()

To get the slider information, you can either use the getInfo() method or subscribe to an Event. Both return an Object:

                container: container, // slider container
               slideItems: slideItems, // slides list
             navContainer: navContainer, // nav container
                 navItems: navItems, // dots list
        controlsContainer: controlsContainer, // controls container
              hasControls: hasControls, // indicate if controls exist
               prevButton: prevButton, // previous button
               nextButton: nextButton, // next button
                    items: items, // items on a page
                  slideBy: slideBy // items slide by
               cloneCount: cloneCount, // cloned slide count
               slideCount: slideCount, // original slide count
            slideCountNew: slideCountNew, // total slide count after initialization
                    index: index, // current index
              indexCached: indexCached, // previous index
             displayIndex: getCurrentSlide(), // display index starts from 1
               navCurrent: navCurrent, // current dot index
         navCurrentCached: navCurrentCached, // previous dot index
                    pages: pages, // visible nav indexes
              pagesCached: pagesCached,
                    sheet: sheet,
                    event: e || {}, // event object if available


Get slider information.


document.querySelector('.next-button').onclick = function () {
  // get slider info
  var info = slider.getInfo(),
      indexPrev = info.indexCached,
      indexCurrent = info.index;

  // update style based on index


Go to specific slide by number or keywords.


document.querySelector('.goto-button').onclick = function () {


Programmatically start slider autoplay when autoplay: true.



Programmatically stop slider autoplay when autoplay: true.



Manually adjust slider height when autoHeight is true.



Destroy the slider.



Rebuild the slider after destroy.

slider = slider.rebuild();
// this method returns a new slider Object with the same options with the original slider

Custom Events

Available events include: indexChanged, transitionStart, transitionEnd, newBreakpointStart, newBreakpointEnd, touchStart, touchMove, touchEnd, dragStart, dragMove and dragEnd.

var customizedFunction = function (info, eventName) {
  // direct access to info object
  console.log(info.event.type, info.container.id);

// bind function to event
slider.events.on('transitionEnd', customizedFunction);

// remove function binding
slider.events.off('transitionEnd', customizedFunction);



.no-js .your-slider { overflow-x: auto; }
.no-js .your-slider > div { float: none; }
