How to make use of it:

1. Include the jQuery library and iCheck plugin within the head section of your web page.

<script src="/path/to/cdn/jquery.min.js"></script>
<script src="/path/to/icheck.min.js"></script>

2. Choose a skin CSS and include it on the net web page.

<!-- All In One -->
<link href="skins/all.css" rel="stylesheet" />

<!-- Flat Theme -->
<link href="skins/flat/red.css" rel="stylesheet" />

<!-- Futurico Theme -->
<link href="skins/futurico/red.css" rel="stylesheet" />

<!-- Line Theme -->
<link href="skins/line/red.css" rel="stylesheet" />

<!-- Minimal Theme -->
<link href="skins/minimal/red.css" rel="stylesheet" />

<!-- Polaris Theme -->
<link href="skins/polaris/red.css" rel="stylesheet" />

<!-- Square Theme -->
<link href="skins/square/red.css" rel="stylesheet" />

3. Create checkboxes and radio buttons on the web page.

<input type="checkbox">
<input type="checkbox" checked>
<input type="radio" name="iCheck">
<input type="radio" name="iCheck" checked>

4. Activate the plugin.

$('input').iCheck({
  checkboxClass: 'icheckbox_minimal',
  radioClass: 'iradio_minimal'
});

5. Full plugin choices with default values.

$('input').iCheck({

  // 'checkbox' or 'radio' to style only checkboxes or radio buttons, both by default
  handle: '',

  // base class added to customized checkboxes
  checkboxClass: 'icheckbox',

  // base class added to customized radio buttons
  radioClass: 'iradio',

  // class added on checked state (input.checked = true)
  checkedClass: 'checked',

  // if not empty, used instead of 'checkedClass' option (input type specific)
  checkedCheckboxClass: '',
  checkedRadioClass: '',

  // if not empty, added as class name on unchecked state (input.checked = false)
  uncheckedClass: '',

  // if not empty, used instead of 'uncheckedClass' option (input type specific)
  uncheckedCheckboxClass: '',
  uncheckedRadioClass: '',

  // class added on disabled state (input.disabled = true)
  disabledClass: 'disabled',

  // if not empty, used instead of 'disabledClass' option (input type specific)
  disabledCheckboxClass: '',
  disabledRadioClass: '',

  // if not empty, added as class name on enabled state (input.disabled = false)
  enabledClass: '',

  // if not empty, used instead of 'enabledClass' option (input type specific)
  enabledCheckboxClass: '',
  enabledRadioClass: '',

  // class added on indeterminate state (input.indeterminate = true)
  indeterminateClass: 'indeterminate',

  // if not empty, used instead of 'indeterminateClass' option (input type specific)
  indeterminateCheckboxClass: '',
  indeterminateRadioClass: '',

  // if not empty, added as class name on determinate state (input.indeterminate = false)
  determinateClass: '',

  // if not empty, used instead of 'determinateClass' option (input type specific)
  determinateCheckboxClass: '',
  determinateRadioClass: '',

  // class added on hover state (pointer is moved onto input)
  hoverClass: 'hover',

  // class added on focus state (input has gained focus)
  focusClass: 'focus',

  // class added on active state (mouse button is pressed on input)
  activeClass: 'active',

  // adds hoverClass to customized input on label hover and labelHoverClass to label on input hover
  labelHover: true,

  // class added to label if labelHover set to true
  labelHoverClass: 'hover',

  // increase clickable area by given % (negative number to decrease)
  increaseArea: '',

  // true to set 'pointer' CSS cursor over enabled inputs and 'default' over disabled
  cursor: false,

  // set true to inherit original input's class name
  inheritClass: false,

  // if set to true, input's id is prefixed with 'iCheck-' and attached
  inheritID: false,

  // set true to activate ARIA support
  aria: false,

  // add HTML code or text inside customized input
  insert: ''

});

6. API strategies.

// check/uncheck
$('input').iCheck('check');
$('input').iCheck('uncheck');

// toggle between states
$('input').iCheck('toggle');

// enable/disable
$('input').iCheck('disable');
$('input').iCheck('enable');

// set state to indeterminate
$('input').iCheck('indeterminate');
$('input').iCheck('determinate');

// apply input changes 
$('input').iCheck('up<a href="#!">date</a>');

// destroy
$('input').iCheck('destroy'); 

7. Event handlers.

$('input').on('ifClicked', function(event){
  // do something
});

$('input').on('ifChanged', function(event){
  // do something
});

$('input').on('ifChecked', function(event){
  // do something
});

$('input').on('ifUnchecked', function(event){
  // do something
});

$('input').on('ifToggled', function(event){
  // do something
});

$('input').on('ifDisabled', function(event){
  // do something
});

$('input').on('ifEnabled', function(event){
  // do something
});

$('input').on('ifIndeterminate', function(event){
  // do something
});

$('input').on('ifDeterminate', function(event){
  // do something
});

$('input').on('ifCreated', function(event){
  // do something
});

$('input').on('ifDestroyed', function(event){
  // do something
});
