/**
 * MediaWiki style sheet for general styles on basic content elements.
 * IMPORTANT: All rules in this file should only apply to __tag__ selectors (T255717).
 * Styling of non-tag selectors is permitted for backwards compatibility, in only two cases:
 * 1) There is an equivalent tag with the same name in HTML4 (e.g. `.small and <small>)
 * 2) A class matches a tag name and is prefixed with `mw-` e.g. `code` and `.mw-code`
 *
 * Styles for basic elements: links, headings, lists, ….
 *
 * This style sheet is used by the Monobook and Vector skins.
