UCX is an attempt to reproduce the recently announced skin for both Fandom and Gamepedia, which will be released in the spring-summer 2021.

Although this code is written just for fun, it works well and has almost all the features of the original Oasis skin. The exception is the Search, which is implemented only partially (clicking on the Fandom logo in the global navigation directs you to the Special:Search). At the moment you can use this code to see how a particular wiki will look like after switching to the new skin.

Remember that this script is a fan script and differs from the actual skin that was released and will be implemented in the future.

Official model of the new skin


  • You can see features of this skin without installing - this page will load the codes automatically.
  • Vertical global navigation.
  • Transparent local navigation.
  • Local navigation scroll together with user
  • Gradient background.
  • Wide dynamic page size.
  • Smaller font of the page header.
  • Redesigned interwiki and contribution buttons.
  • Table of contents looks like mobile one.
  • The Search opens when you click the Fandom logo on the top left.


It is highly recommended to install both the CSS and JS since JavaScript takes 1 second to load after opening a page. Installing the CSS will pre-load the style first.
