Usage

1. Include jQuery, photor.min.js and photor.min.css:

   <script src="//ajax.googleapis.colim/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
   
   <link  href="photor.min.css" rel="stylesheet"> <!-- 1.4 KB in gzip -->
   <script src="photor.min.js"></script> <!-- 5 KB in gzip -->

2. Add some HTML:

   <div class="photor">
   
       <div class="photor__viewport">
   
           <div class="photor__viewportLayer">
   
               <!-- Add photos -->
               <img src="images/1.jpg" data-thumb="thumbs/1.jpg">
               <img src="images/2.jpg" data-thumb="thumbs/2.jpg">
   
           </div>
   
           <div class="photor__viewportControl">
               <div class="photor__viewportControlPrev"></div>
               <div class="photor__viewportControlNext"></div>
           </div>
   
       </div>
   
       <div class="photor__thumbs">
           <div class="photor__thumbsWrap"></div>
       </div>
   
   </div>

   Note: data-thumb contains a path to the thumbnail.

3. Initialize Photor:

   <script>
       $(document).ready(function() {
           $('.photor').photor();
       });
   </script>

How to build

1. Make sure you have nodejs, npm and grunt-cli installed;

2. When in your project folder, run

   git clone git@github.com:2gis/photor.git
   cd photor

   to clone this repo into a new subfolder and jump into it;

3. Run

   npm install
   grunt

   to install all dependencies and build Photor;

Optional task grunt dev builds Photor as well as starts a web server on port 3000, and runs a watcher that rebuilds the project on file change.

Configuration

You can specify parameters on initialization.

$('.photor').photor({

    // General options
    current: 0,           // {Number}  Index of start slide
    duration: 300,        // {Number}  Transition duration
    loop: false,          // {Boolean} Loop gallery
    slidesOnScreen: 1,    // {Number}  Number of visible slides in viewport

    // Handlers
    single: false,        // {Boolean} Initialize event handlers if gallery contains only one photo?
    keyboard: true,       // {Boolean} Initialize keyboard event handlers?

    // Prefixes
    slideIdPrefix: '_',   // {String}  Prefix for class with slide index (e.g. "_12")
    ieClassPrefix: '_ie', // {String}  Prefix for class with IE version (e.g. "_ie8")

    // Classnames
    control: 'photor__viewportControl',

    _animated: '_animated',     // Animation in progress
    _hidden: '_hidden',         // Slide is hidden

    // Algorithm
