    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
    // bind function to event'transitionEnd', customizedFunction);
    // remove function binding'transitionEnd', customizedFunction);
