Clay is a dark style family for WoltLab Suite 5 of 3 different color variants (2 if you're using WoltLab Suite 5.2). The available color options are: Turquoise, pink or orange. The style has modern background effects that resemble Microsoft’s Fluent Design.

With version 5.2 this style comes with style options making it easier for you to customize the style without having to tinker with code.

As always: Well structured and clean modern modular SCSS code help to make this style a beauty at the backend too. Although you now might not need to look there. Clay is build to work with all apps currently available by WoltLab: Core (of course), Forum, Filebase, Blog, Calendar and Gallery. If third party developers stuck with WoltLab Suite's standards this style will also be compatible with their plugins or apps out of the box.

If you're running this style in a multilingual system: There are language variables available for Clay in German, English, French and Spanish. You can add more language variables.
