Feature summary (what you would like to be able to do and where):
There have been several discussions on how to use Codex styles in wikitext. It seems to me that the basic needs should be satisfied by an extension with which it is possible to create the main components of the Codex: Button, Card, Label, Message, SearchInput (aka MediaWiki-extensions-InputBox), Tabs.
Benefits (why should this be implemented?):
This will allow communities to create more uniform designs in an easy way.
