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:

Enabling the `normalize` feature is recommended
Without this, you may notice some elements look a little off.

visualClear
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 for links to non-existent pages.
Skins using the legacy feature currently get red link color of. Skins that use the content feature will get a color of.

For skins that do not import either, these links will appear as normal links.

Suggested:

Skins using `error`, `warning` or `success` classes should provide their own styles

 * Consider using `mw-messagebox`, `mw-warningbox` and `mw-successbox` instead.

Print elements
Only skins using the interface feature will hide elements with the `printfooter` class automatically.

Ajax spinners
There will no longer be defaults for mw-ajax-loader and mw-small-spinner. Copy the styles if they are needed.
