A living style guide offers improved documentation of the visual appearance and behavior of a site.
Unlike a static style guide (say, a wiki page or PDF), it is generated on-the-fly from the actual HTML, CSS, and JavaScript used in production.[1][2] This allows us to view styles as they are live on the site, and inline comments can be added to document the purpose of a particular style or set of styles.

MediaWiki currently has one style guide (the other 2 are outdated, see task T51117 and task T51117#2808532):


Starting with release 1.25, when you use OOjs UI components within MediaWiki, they use its MediaWiki theme which is very similar to mediawiki.UI.


OOjs UI style guide[edit]

Under active development, subject to change

This style guide runs on MediaWiki and uses the OOUIPlayground extension to turn descriptions of OOjs UI components in wiki pages into PHP and JavaScript code snippets, and to invoke the actual components. The extension simulates visual disabilities like Protanopia and Monochromacy, using SVG filters. Plans include the ability to simulate other accessibility issues and mobile views on desktop. The guide uses Blueprint, a simple purpose-built skin that highlights the component library without distraction.

In addition to per-component documentation, the guide will also have guidelines on typography, iconography, and how to compose elements.

mediawiki.UI style guide[edit]

A Makefile in core builds a static styleguide from the contents of files in resources/src/mediawiki.ui using kss-node. The generated HTML is published to . (Continuous integration should rebuild this styleguide as needed at, phab:T60620)

The downside of being standalone is you can't see how how styles behave with different skins and Beta features enabled.
