Manual:Skinning/Vector

How to create a skin FooBar based on the default skin Vector (any name other than FooBar will do of course) in MediaWiki 1.17/1.18

copy vector

 * copy directory ./skins/vector to ./skins/foobar
 * copy ./skins/Vector.php to ./skins/FooBar.php
 * copy ./skins/Vector.deps.php to ./skins/FooBar.deps.php
 * in ./skins/FooBar.php, change:
 * everywhere SkinVector into SkinFooBar</tt>
 * everywhere VectorTemplate</tt> into FooBarTemplate</tt>
 * $skinname = 'vector', $stylename = 'vector'</tt> into $skinname = 'foobar', $stylename = 'foobar'</tt>
 * 'skins.vector' into 'skins.foobar'
 * leave other 'vector' occurrences intact, unless you're going to add all vector-related system messages...
 * register your skin's module by putting the following in $IP/resources/Resources.php</tt>:

colors
The color scheme used in vector is primarily maintained in a bunch of images in ./skins/foobar/images</tt> driven by ./skins/foobar/screen.css</tt>
 * border.png</tt>: color of borders of the contents area
 * page-base.png</tt>: background of page apart from contents
 * page-fade.png</tt>: color fade at top of page
