Extension:Tabs/de-formal

The Tabs extension makes it possible to insert tab menus, dropdown menus, and collapsible boxes into any page, using the and  tags, or the   parser function. This extension requires no JavaScript to work, except for older browsers such as Internet Explorer 8 and lower as a CSS  polyfill. As opposed to other extensions, this independence from JavaScript results in having no flash of unstyled content when the page loads.

Configuration
None, but the default background colour for dropdown menus is stored on the "MediaWiki:tabs-dropdown-bgcolor" page.

Usage
See.
