Manual:Skins

Skins allow users to customize the look and feel of MediaWiki. MediaWiki's default skin is Vector. A number of other skins also exist in default MediaWiki installations. Users can see which skins are available on their preferences page. To see some examples of skins that other sites using MediaWiki have created, see Sites using MediaWiki/gallery and the Skin namespace on this wiki. It is important to note that optional components, such as JavaScript, may only function properly on a specific skin.
