@dangerousthings/tailwind-preset

Tailwind CSS v3 preset that maps Dangerous Things design tokens to Tailwind theme values. Uses CSS custom property references so the same utility classes work across both DT and Classic brands at runtime.

Install

npm install @dangerousthings/tailwind-preset

Peer Dependencies

npm install tailwindcss@^3.4

You also need a brand token CSS file loaded (from @dangerousthings/web or @dangerousthings/tokens).

Setup

Add the preset to your tailwind.config.js:

import dtPreset from "@dangerousthings/tailwind-preset";

export default {
  presets: [dtPreset],
  content: ["./src/**/*.{tsx,ts,html}"],
};

Available Utilities

Colors

All DT design token colors are available under the dt- prefix. Colors with -rgb variants support Tailwind opacity modifiers.

<div class="bg-dt-bg text-dt-text-primary">
  <h1 class="text-dt-primary">Heading</h1>
  <p class="text-dt-text-secondary">Body text</p>
  <button class="bg-dt-primary/50 text-dt-bg">50% opacity</button>
</div>

| Utility | Token | |---------|-------| | bg-dt-bg, text-dt-bg | --color-bg | | bg-dt-surface | --color-surface | | bg-dt-primary, text-dt-primary | --color-primary | | bg-dt-secondary | --color-secondary | | bg-dt-accent | --color-accent | | bg-dt-error | --color-error | | text-dt-text-primary | --color-text-primary | | text-dt-text-secondary | --color-text-secondary | | text-dt-text-muted | --color-text-muted |

Mode Colors

Card mode colors are available under the mode- prefix:

<div class="border-mode-normal">Normal</div>
<div class="text-mode-emphasis">Emphasis</div>
<div class="bg-mode-warning">Warning</div>

Spacing

<div class="p-dt-4 gap-dt-2 m-dt-1">...</div>

| Utility | Token | |---------|-------| | *-dt-1 through *-dt-8 | --space-1 through --space-8 |

Border Radius

<div class="rounded-dt">Default</div>
<div class="rounded-dt-sm">Small</div>
<div class="rounded-dt-lg">Large</div>

Font Family

<h1 class="font-dt-heading">Tektur heading</h1>
<p class="font-dt-body">Body text</p>
<code class="font-dt-mono">Monospace</code>

Brand Switching

Because the preset uses var() references, switching brands at runtime requires only changing the CSS custom properties (e.g., via data-brand attribute). No Tailwind rebuild is needed.

<div data-brand="dt">Cyan neon theme</div>
<div data-brand="classic">Navy magenta theme</div>
