Rofi RASI Theming

Overview

RASI (Rofi Advanced Style Information) is a CSS-inspired theming system for rofi 2.0+. It provides a fixed widget tree with box-model styling, global variables, calc(), @media queries, and linear gradients. Think CSS circa 2008 + custom properties + calc() applied to a box-packing layout engine. No animations, no transforms, no hover states.

When to Use

• User wants to create or modify a .rasi theme
• Porting a color scheme / design to rofi
• Debugging layout or styling issues in rofi
• Building creative layouts (grid launchers, decorated panels, Spotlight-style bars)

Widget Tree

Fixed hierarchy — you cannot invent widget types, but you CAN restructure with children: and inject custom widgets via naming prefixes.
