Crate tangible 

Design tokens as data — colors, type, space, shadows, gradients, and contrast — rendered to CSS.

tangible turns a structured token specification into a CSS custom-property sheet you can drop into any project. It is the library that powers the tangible command-line tool, but every step in the pipeline (parsing, resolving palettes, picking inks, emitting CSS) is available programmatically for embedding in build scripts, generators, or design-system tooling.

At a glance

use tangible::{Renderer, Spec};

let json = std::fs::read_to_string("tokens.json")?;
let spec: Spec = serde_json::from_str(&json)?;
let manifest = Renderer::new().render(&spec)?;
std::fs::write("dist/tokens.css", manifest.to_string())?;

Modules

• color — color definitions, gradients, interpolation, sampling.
• contrast — WCAG-driven ink selection for legible text on arbitrary backgrounds.
• spec — the Spec structure and its sub-types (the input format).
• render — the Renderer, its Config, and the resulting Manifest.
