Manual:ResourceLoaderSkinModule

ResourceLoaderSkinModule is a special kind of module that provides boilerplate styles to help you build a working skin. It can be used by registering a module in your skin's skin.json file like so:

For skins deprecating the legacy feature

 * Enabling the `normalize` feature is recommended.
 * Skins making use of `visualClear` should instead use the clear fix mix in. To aid migrating add the following style to your skin:
 * Skins should define a red link color e.g. Skins using `error`, `warning` or `success` classes should provide their own styles and consider using `mw-messagebox`, `mw-warningbox` and `mw-successbox` instead.

Skins using the `printfooter` class will now need to hide this element by default. There will no longer be defaults for mw-ajax-loader and mw-small-spinner. Copy the styles if they are needed.
