# EVA CSS > A fluid SCSS framework that turns a static design into a responsive system using CSS clamp() and OKLCH colors. Generated from the documentation source. Human-readable version: https://eva-css.xyz/doc/index.html ## Documentation - [Getting started](https://eva-css.xyz/doc/index.html) — What EVA CSS is, the two ideas it is built on, and a working setup in three commands. - [Installation](https://eva-css.xyz/doc/install.html) — The three packages, the four SCSS entry points, and how to compile and watch. - [Configuration](https://eva-css.xyz/doc/config.html) — Every option accepted by the SCSS entry points, what it changes in the output, and the two build modes. - [Fluid sizing](https://eva-css.xyz/doc/sizes.html) — The four scaling variants, the separate font-size namespace, and switching a subtree from viewport to container. - [Colors](https://eva-css.xyz/doc/colors.html) — Five roles, three numbers each, and everything else recomposed in OKLCH — opacity fades, brightness steps, per-role tuning and dark mode. - [Gradients](https://eva-css.xyz/doc/gradients.html) — Composable gradient classes — one applier, then setters for colors, direction, zoom and animation. - [Utility classes](https://eva-css.xyz/doc/utilities.html) — Every class emitted when $build-class is true — sizing, color, flex, grid, typography and layout. - [Golden grid](https://eva-css.xyz/doc/golden-grid.html) — The opt-in page grid — four unequal tracks derived from the golden ratio, named lines, and an editorial flow carried by subgrid. - [Adopting EVA](https://eva-css.xyz/doc/adopt.html) — Wiring EVA into a project that already ships — the px audit, fusing near-duplicates, aliasing design tokens, and the traps. - [CLI tools](https://eva-css.xyz/doc/cli.html) — eva-color for OKLCH conversion, palettes, themes and contrast; eva-purge for stripping the classes you never used. - [Reference](https://eva-css.xyz/doc/reference.html) — Every option, token and class in one flat list. ## Links - Website: https://eva-css.xyz - GitHub: https://github.com/nkdeus/eva - npm: eva-css-fluid, eva-colors, eva-css-purge - Full text: https://eva-css.xyz/llms-full.txt
