token_system.css in CSS

A whole small design system: tokens, themes, a type scale, and the components built on them.

/* A small design system: raw values, decisions, then components. */

@layer reset, tokens, base, components, utilities;

@layer tokens {
  :root {
    color-scheme: light dark;

  :focus-visible { outline: var(--ring); outline-offset: 2px; }
}

@layer components {
  .card {
    display: grid;
    grid-template-rows: auto 1fr auto;
    gap: var(--space-3);
    padding: var(--space-4);
    background: var(--surface);
    border: 1px solid var(--edge);
    border-radius: var(--radius);
  }

  .card__meta { color: var(--text-muted); font-size: 0.875rem; }

  .button {
    padding: var(--space-2) var(--space-4);
    border: 0;
    border-radius: var(--radius);
    background: var(--accent);
    color: white;
    transition: background 120ms ease;
  }

  .button:hover { background: var(--accent-hover); }
  .button:disabled { background: var(--edge); color: var(--text-muted); }

  .badge {
    display: inline-flex;
    padding: var(--space-1) var(--space-3);
    border-radius: 999px;
    background: color-mix(in oklab, var(--accent) 15%, transparent);
    font-size: 0.8125rem;
  }
}

@layer utilities {
  .stack { display: grid; gap: var(--gap, var(--space-4)); }
  .cluster { display: flex; flex-wrap: wrap; gap: var(--space-2); }
  .center { margin-inline: auto; max-inline-size: 68ch; }
}

How it works

  1. Every component reads tokens; none of them names a color.
  2. Dark mode changes the token layer and nothing else.
  3. The layers make the order explicit, so a utility always wins.
