skin.txt MediaWiki includes four core skins: * Vector: The default skin. Introduced in the 1.16 release (2010), it has been set as the default in MediaWiki since the 1.17 release (2011), replacing Monobook. * Monobook: Named after the black-and-white photo of a book in the page background. Introduced in the 2004 release of 1.3, it had been been the default skin since then, before being replaced by Vector. * Modern: An attractive blue/grey theme with sidebar and top bar. Derived from Monobook. * Cologne Blue: A lightweight skin with minimal formatting. The oldest of the currently bundled skins, largely rewritten in 2012 while keeping its appearance. Several legacy skins were removed in the 1.22 release, as the burden of supporting them became too heavy to bear. Those were: * Standard (a.k.a. Classic): The old default skin written by Lee Crocker during the phase 3 rewrite, in 2002. * Nostalgia: A skin which looks like Wikipedia did in its first year (2001). This skin is now used for the old Wikipedia snapshot at http://nostalgia.wikipedia.org/ * Chick: A lightweight Monobook skin with no sidebar. The sidebar links were given at the bottom of the page instead. * Simple: A lightweight skin with a simple white-background sidebar and no top bar. * MySkin: Essentially Monobook without the CSS. The idea was that it could be customised using user-specific or site-wide CSS (see below). == Custom CSS/JS == It is possible to customise the site CSS and JavaScript without editing any server-side source files. This is done by editing some pages on the wiki: * [[MediaWiki:Common.css]] -- for skin-independent CSS * [[MediaWiki:Common.js]] -- for skin-independent JavaScript * [[MediaWiki:Vector.css]], [[MediaWiki:Monobook.css]], etc. -- for skin-dependent CSS * [[MediaWiki:Vector.js]], [[MediaWiki:Monobook.js]], etc. -- for skin-dependent JavaScript These can also be customised on a per-user basis, by editing [[User:/vector.css]], [[User:/vector.js]], etc. This feature has led to a wide variety of "user styles" becoming available: http://www.mediawiki.org/wiki/Manual:Gallery_of_user_styles If you want a different look for your wiki, that gallery is a good place to start. == Drop-in custom skins == If you put a file in MediaWiki's skins directory, ending in .php, the name of the file will automatically be added as a skin name, and the file will be expected to contain a class called Skin with the skin class. You can then make that skin the default by adding to LocalSettings.php: $wgDefaultSkin = ''; You can also disable dropped-in or core skins using: $wgSkipSkins[] = ''; This technique is used by the more ambitious MediaWiki site operators, to create complex custom skins for their wikis. It should be preferred over editing the core Monobook skin directly. See http://www.mediawiki.org/wiki/Manual:Skinning for more information. == Extension skins == It is now possible (since MediaWiki 1.12) to write a skin as a standard MediaWiki extension, enabled via LocalSettings.php. This is done by adding it to $wgValidSkinNames, for example: $wgValidSkinNames['mycoolskin'] = 'MyCoolSkin'; and then registering a class in $wgAutoloadClasses called SkinMycoolSkin, which derives from Skin. This technique is apparently not yet used (as of 2008) outside the DumpHTML extension.
