About 80 templates in the wiki contain CSS style instead of using a CSS class which will unify the styling and reduce the maintenance effort in case we want to change some styles in the whole wiki one day.

This is the wiki: http://en.opensuse.org . Styles should be moved to CSS classes, temporarily to MediaWiki:Common.css, to test how they work, and later to the bento CSS file. As student will have no admin access to server, or wiki, mentor has to take care that solutions are included in MediaWiki:Common.css and later moved to server. Student can update templates to use new defined classes. This is even more important for templates that are used as page templates because those are copied to the new page, which means we'd have to change all pages based on this template. See http://en.opensuse.org/Help:CSS_cleanup for more details.
