+ skin.js
+ =========
+
+ In this file we interact with the CKEditor JavaScript API to register the skin
+ and enable additional skin related features.
+
+ The level of complexity of this file depends on the features available in the
+ skin. There is only one mandatory line of code to be included here, which is
+ setting CKEDITOR.skin.name. All the rest is optional, but recommended to be
+ implemented as they make higher quality skins.
+
+ For this skin, the following tasks are achieved in this file:
+
+ 1. Register the skin.
+ 2. Register browser specific skin files.
+ 3. Define the "Chameleon" feature.
+ 4. Register the skin icons, to have them used on the development version of
+ the skin.
+ */
+
+// 1. Register the skin
+// ----------------------
+// The CKEDITOR.skin.name property must be set to the skin name. This is a
+// lower-cased name, which must match the skin folder name as well as the value
+// used on config.skin to tell the editor to use the skin.
+//
+// This is the only mandatory property to be defined in this file.
+CKEDITOR.skin.name = 'husky';
+
+// 2. Register browser specific skin files
+// -----------------------------------------
+// (http://docs.cksource.com/CKEditor_4.x/Skin_SDK/Browser_Hacks)
+//
+// To help implementing browser specific "hacks" to the skin files and have it
+// easy to maintain, it is possible to have dedicated files for such browsers,
+// for both the main skin CSS files: editor.css and dialog.css.
+//
+// The browser files must be named after the main file names, appended by an
+// underscore and the browser name (e.g. editor_ie.css, dialog_ie8.css).
+//
+// The accepted browser names must match the CKEDITOR.env properties. The most
+// common names are: ie, opera, webkit and gecko. Check the documentation for
+// the complete list:
+// http://docs.ckeditor.com/#!/api/CKEDITOR.env
+//
+// Internet explorer is an exception and the browser version is also accepted
+// (ie7, ie8, ie9, ie10), as well as a special name for IE in Quirks mode (iequirks).
+//
+// The available browser specific files must be set separately for editor.css
+// and dialog.css.
+CKEDITOR.skin.ua_editor = 'ie,iequirks,ie7,ie8,gecko';
+CKEDITOR.skin.ua_dialog = 'ie,iequirks,ie7,ie8,opera';
+
+// 3. Define the "Chameleon" feature
+// -----------------------------------
+// (http://docs.cksource.com/CKEditor_4.x/Skin_SDK/Chameleon)
+//
+// "Chameleon" is a unique feature available in CKEditor. It makes it possible
+// to end users to specify which color to use as the basis for the editor UI.
+// It is enough to set config.uiColor to any color value and voila, the UI is
+// colored.
+//
+// The only detail here is that the skin itself must be compatible with the
+// Chameleon feature. That's because the skin CSS files are the responsible to
+// apply colors in the UI and each skin do that in different way and on
+// different places.
+//
+// Implementing the Chameleon feature requires a bit of JavaScript programming.
+// The CKEDITOR.skin.chameleon function must be defined. It must return the CSS
+// "template" to be used to change the color of a specific CKEditor instance
+// available in the page. When a color change is required, this template is
+// appended to the page holding the editor, overriding styles defined in the
+// skin files.
+//
+// The "$color" placeholder can be used in the returned string. It'll be
+// replaced with the desired color.
+CKEDITOR.skin.chameleon = (function() {
+    // This method can be used to adjust colour brightness of various element.
+    // Colours are accepted in 7-byte hex format, for example: #00ff00.
+    // Brightness ratio must be a float number within [-1, 1],
+    // where -1 is black, 1 is white and 0 is the original colour.
+    var colorBrightness = (function() {
+            function channelBrightness(channel, ratio) {
+                return ( '0' + ( ratio < 0 ?
+                    0 | channel * ( 1 + ratio )
+                    :
+                    0 | channel + ( 255 - channel ) * ratio ).toString(16)
+                    ).slice(-2);
+            }
+
+            return function(hexColor, ratio) {
+                var channels = hexColor.match(/[^#]./g);
+
+                for (var i = 0; i < 3; i++)
+                    channels[ i ] = channelBrightness(parseInt(channels[ i ], 16), ratio);
+
+                return '#' + channels.join('');
+            };

+    // several places of our template.

+// ----------------------------------------------------------
+// (http://docs.cksource.com/CKEditor_4.x/Skin_SDK/Icons)
+//
+// Note: As "moono" is the default CKEditor skin, it provides no custom icons,
+// thus this code is commented out.
+//
+// This code is here just to make the skin work fully when using its "source"
+// version. Without this, the skin will still work, but its icons will not be
+// used (again, on source version only).
+//
+// This block of code is not necessary on the release version of the skin.
+// Because of this it is very important to include it inside the REMOVE_START
+// and REMOVE_END comment markers, so the skin builder will properly clean
+// things up.
+//
+// If a required icon is not available here, the plugin defined icon will be
+// used instead. This means that a skin is not required to provide all icons.
+// Actually, it is not required to provide icons at all.
+//
+// (function() {
+//		// The available icons. This list must match the file names (without
+//		// extension) available inside the "icons" folder.
+//		var icons = ( 'about,anchor-rtl,anchor,bgcolor,bidiltr,bidirtl,blockquote,' +
+//			'bold,bulletedlist-rtl,bulletedlist,button,checkbox,copy-rtl,copy,' +
