ExpressiveCSS

A CSS framework inspired by Google's Material Design 3 Expressive design language. Built on top of MaterializeCSS v2.2.2, ExpressiveCSS aims to bring the expressive, dynamic, and personality-rich aesthetics of M3 Expressive to the web.

Status: Early Alpha — Actively under development. APIs and class names may change. Not yet recommended for production use.

Vision

Google's M3 Expressive introduces a more vibrant, playful, and emotionally resonant layer to Material Design — prioritizing personality, motion, and visual richness. ExpressiveCSS brings that vision to a CSS framework you can drop into any project.

The framework uses MaterializeCSS v2.2.2 as its foundation, which will be progressively updated and reshaped to match the M3 Expressive design language.

Project Structure

src/scss/
├── materialize.scss          # Entry point
├── foundation/               # Design tokens, theme, variables, color palette, mixins, normalize, base
├── utilities/                # Colors, typography, elevation, spacing, responsive, helpers
├── layout/                   # Grid, footer, table
├── components/               # 28 UI components (buttons, cards, appbar, modal, etc.)
└── forms/                    # Input fields, radio buttons, checkboxes, switches, select, file input, range

The framework loads in a layered dependency order: foundation → utilities → layout → components → forms, ensuring design tokens and variables are available before any component uses them.
