## 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`

    <script>
      var slider = tns({
        container: '.my-slider',
        items: 1,
        responsive: {
          640: {
            edgePadding: 20,
            gutter: 20,
            items: 2
          },
          700: {
            gutter: 30
          },
          900: {
            items: 3
          }
        }
      });
    </script>

NOTE:

- 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↑

## Methods

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
    };

#### getInfo

Get slider information.

    slider.getInfo();

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

      // update style based on index
      info.slideItems[indexPrev].classList.remove('active');
      info.slideItems[indexCurrent].classList.add('active');
    };

#### goTo

Go to specific slide by number or keywords.

    slider.goTo(3);
    slider.goTo('prev');
    slider.goTo('next');
    slider.goTo('first');
    slider.goTo('last');

    document.querySelector('.goto-button').onclick = function () {
      slider.goTo(3);
    };

#### play

Programmatically start slider autoplay when `autoplay: true`.

    slider.play();

#### pause

Programmatically stop slider autoplay when `autoplay: true`.

    slider.pause();

#### updateSliderHeight

Manually adjust slider height when `autoHeight` is `true`.

    slider.updateSliderHeight();

#### destroy

Destroy the slider.

    slider.destroy();

#### rebuild

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);
