+ * Common skin styles, grouped into three graded levels.
+ *
+ * Level 1 "elements":
+ * The base level that only contains the most basic of common skin styles.
+ * Only styles for single elements are included, no styling for complex structures like the TOC
+ * is present. This level is for skins that want to implement the entire style of even content area
+ * structures like the TOC themselves.
+ *
+ * Level 2 "content":
+ * The most commonly used level for skins implemented from scratch. This level includes all the single
+ * element styles from "elements" as well as styles for complex structures such as the TOC that are output
+ * in the content area by MediaWiki rather than the skin. Essentially this is the common level that lets
+ * skins leave the style of the content area as it is normally styled, while leaving the rest of the skin
+ * up to the skin implementation.
+ *
+ * Level 3 "interface":
+ * The highest level, this stylesheet contains extra common styles for classes like .firstHeading, #contentSub,
+ * et cetera which are not outputted by MediaWiki but are common to skins like MonoBook, Vector, etc...
+ * Essentially this level is for styles that are common to MonoBook clones. And since practically every skin
+ * that currently exists within core is a MonoBook clone, all our core skins currently use this level.
+ *
+ * These modules are typically loaded by addModuleStyles which has absolutely no concept of dependency
+ * management. As a result the skins.common.* modules contain duplicate stylesheet references instead of
+ * setting 'dependencies' to the lower level the module is based on. For this reason avoid including multiple
+ * skins.common.* modules into your skin as this will result in duplicate css.
