Apex is a skin designed to respond to screens of different sizes. It is a concept still under development. One of its key features is pulling the table of contents out into a fly-out menu on the right of the page, making it accessible without overpowering the page.

This skin may not work correctly on mobile devices.


  • If using Vagrant , install with vagrant roles enable apex -p

Manual installation

  • Download and place the file(s) in a directory called apex in your skins/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
wfLoadSkin( 'apex' );
  •   Done - Navigate to Special:Version on your wiki to verify that the skin is successfully installed.

To users running MediaWiki 1.24 or earlier:

The instructions above describe the new way of installing skins using wfLoadSkin(), since MediaWiki 1.25. If you need to install this skin in earlier versions, instead of wfLoadSkin( 'apex' );, you need to use:

require_once "$IP/skins/apex/apex.php";

(To run a skin on an earlier release, you may need to download the version of it tagged for that release from Special:SkinDistributor.)
