Custom HTML structure

<divid="tabs">
  <div>
    <button type="button" data-target="tab-1">Tab 1</button>
    <button type="button" data-target="tab-2">Tab 2</button>
    <button type="button" data-target="tab-3">Tab 3</button>
  </div>
  <div>
    <div data-content="tab-1">Content of first tab</div>
    <div data-content="tab-2">Content of second tab</div>
    <div data-content="tab-3">Content of third tab</div>
  </div>
</div>

new Tabit(
  document.getElementById('tabs'),
  {
    buttonSelector: '[data-target]',
    contentSelector: '[data-content]',
    buttonAttribute: 'data-target',
    contentAttribute: 'data-content',  
  }
);

Only change CSS class

new Tabit(
  document.getElementById('tabs'),
  {
    contentActiveClass: 'is-active',
    toggleDisplay: false
  }
);

div:not(.is-active) {
  position: absolute;
  width: 1px;
  height: 1px;
  padding: 0;
  margin: -1px;
  overflow: hidden;
  clip: rect(0, 0, 0, 0);
  border: 0;
}

Change on hover

new Tabit(
  document.getElementById('tabs'),
  {
    event: ['mouseover', 'click']
  }
);

Use custom animations

new Tabit(
  document.getElementById('tabs'),
  {
    toggleDisplay: false,
    onInit: function (instance) {
      this.tabs.forEach(function (item, i) {
        if (i !== 0) $(item.content).hide();
      });
    },
    beforeChange: function (activeTab, newTab, instance) {
      if (!activeTab) return; // no animate on init
      $(activeTab.content)
        .stop()
        .fadeOut(function () {
          $(newTab.content).stop().fadeIn()
        });
    }
  }
);

Auto rotation

var tabit = new Tabit(document.getElementById('tabs'));
var rotate = setInterval(function() {
  tabit.next();      
}, 2000)
