Salesforce Lightning Design System
Salesforce's official CSS/HTML design system for building apps that look like Salesforce. If you're building on the Lightning platform or need to match Salesforce's UI exactly, this is the canonical source. Outside that context, it's not useful — the entire visual language is Salesforce-specific.
The design token system is well-structured: tokens are split into primitives, aliases, and component-level values across YAML files, which makes theming traceable. Accessibility is treated seriously — there's a dedicated axe/a11y test pipeline and per-component a11y linting in CI, not just a checkbox. The Storybook-based development workflow gives you isolated component development with documented variants. Token output format is pluggable via a custom formats directory, so you can emit CSS custom properties or whatever your pipeline needs.
Node 14 is pinned in the nvmrc — that's a three-major-versions-old EOL runtime, which signals the toolchain hasn't kept up. Travis CI badges in the README while the actual workflows are GitHub Actions is the kind of drift that suggests documentation isn't getting the same attention as the components. There's no framework-agnostic component library here — you get HTML markup and CSS classes, not React or Web Components, so you're on your own for interactivity. The whole thing is only useful if you're shipping inside or adjacent to Salesforce; there's zero path to adopting this for a non-Salesforce product without ripping out every visual decision they've made.
