About Adwaita-for-Steam

Adwaita-for-Steam is an open-source skin that makes the Steam client look more like a native GNOME app. It offers multiple color themes, light, dark or automatic color schemes, accent colors, font choices, window control styles and layouts, optional extras, and support for loading custom CSS.

The primary installation method is an installer script that patches Steam files without third-party CSS injectors; AdwSteamGtk, Millennium, CSSLoader, and SFP are also supported. Steam updates may reset the theme and require reinstallation, Store, Community and profile pages are no longer themable with the primary method, and not all elements can be rounded.
