A library containing all tokens (colors, spacings, font formatting, etc.) and assets (fonts, icons) of DB UX Design System v3.
We currently support:
npm i @db-ui/foundationsYou use this library if you need some colors, spacings etc.
tl;dr: Use the default theme and the bundled styles by importing
default-theme.css&&db-ui-foundations[-absolute|-rollup|-webpack].css.
First of all you need to import a theme which contains all tokens (css-properties). We provide a default-theme.css which handles dark/light mode as well.
Afterward, you may import helper classes / placeholders to easily consume the tokens from your theme. There are some categories:
-
init: Global styles which apply to all or a large group of selectors. Make sure to import
inits/required.cssto normalize tags likebodyetc. Furthermore, we provide some default styles. -
icons: Icons classes to load woff2 files and adds
[data-icon]and[data-icon-after]to enable icons for all tags and components. - helpers: Use dividers or focus border
-
fonts: Overwrite default
font-size,line-heightandicon-size - density: Overwrite default density to scale adaptive components inside container using density
- colors: Sets an adaptive color to a container, which passes all required css-properties to children
You can import the complete init styles with db-ui-foundations[-absolute|-rollup|-webpack].css which apply the default:
-
Density:
regular -
Adaptive Coloring:
neutral-bg-lvl-1
Default assets path for db-ui-foundations.css is ../assets. Make sure to copy all used resources like icons and fonts into your public folder before build. Or you use a modern bundler which handles bundling for you. In this case use db-ui-foundations[-rollup|-webpack].css.
Import the styles in your main .js | .ts file or in your main .css file.
CSS:
/* index.css */
@import "@db-ui/foundations/build/css/default-theme.css";

@import "@db-ui/foundations/build/css/colors/classes/all.css";JS/TS:
// main.[js|ts]

import "@db-ui/foundations/build/css/fonts/classes/all.css";
/* Optional: Use [data-color] everywhere */
import "@db-ui/foundations/build/css/colors/classes/all.css";In CSS:
.my-container {
padding: var(--db-spacing-fixed-md);
}In HTML:
<!-- With classes-->
<div
data-density="functional"
class="db-successful-bg-lvl-1 my-container"
></div>
<!-- With data attributes-->
<div
class="my-container"
data-density="functional"
data-color="successful-bg-lvl-1"
></div>Note: In CSS you might to use the classes or data-attributes even more because you cannot use placeholders or mixins like we have it in scss. If you use a 3rd party library and cannot apply classes or data-attributes you might want to copy the content of our helper classes to apply it to the 3rd party class.
Default assets path for db-ui-foundations.scss is ../assets. Make sure to copy all used resources like icons and fonts into your public folder before build. Or you use a modern bundler which handles bundling for you. In this case use db-ui-foundations[-rollup|-webpack].scss.
Import the styles in your main .js | .ts file or in your main .scss file.
SCSS:

@forward "@db-ui/foundations/build/scss/colors/classes/all";Note: Besides of forwarding the classes you can use placeholders to include only some specific styles.
JS/TS:
// main.[js|ts]
import "@db-ui/foundations/build/scss/default-theme.scss";
import "@db-ui/foundations/build/scss/db-ui-foundations.scss";
/* Optional: Use [data-icon] everywhere */
import "@db-ui/foundations/build/scss/icons/include.scss";

import "@db-ui/foundations/build/scss/fonts/classes/all.scss";
/* Optional: Use [data-color] everywhere */
import "@db-ui/foundations/build/scss/colors/classes/all.scss";In SCSS:
@use "@db-ui/foundations/build/scss/variables";
.my-container {
padding: variables.$db-spacing-fixed-md;
}In SCSS with placeholder:
@use "@db-ui/foundations/build/scss/fonts";
@use "@db-ui/foundations/build/scss/colors";
.placeholder-container {
@extend %db-overwrite-font-size-sm;
@extend %db-successful-bg-lvl-1;
}In HTML:
<!-- With classes-->
<div
data-density="functional"
class="db-successful-bg-lvl-1 my-container"
></div>
<!-- With data attributes-->
<div
class="my-container"
data-density="functional"
data-color="successful-bg-lvl-1"
></div>Check the required imports for CSS to enable all tokens and defaults. After this you can extend your tailwind config like this:
//tailwind.config.js
/** @type {import('tailwindcss').Config} */
import tokens from "@db-ui/foundations/build/tailwind/tailwind-tokens.json";
export default {
content: ["./index.html", "./src/**/*.{js,jsx,ts,tsx}"],
plugins: [],
theme: {
...tokens,
gap: ({ theme }) => ({
...theme("spacing")
}),
space: ({ theme }) => ({
...theme("spacing")
})
}
};//tailwind.config.ts
import type { Config } from "tailwindcss";
import { CustomThemeConfig } from "tailwindcss/types/config";
import tokens from "@db-ui/foundations/build/tailwind/tailwind-tokens.json";
const customThemeConfig: CustomThemeConfig = tokens as any;
export default {
content: [],
theme: {
...customThemeConfig,
gap: ({ theme }) => ({
...theme("spacing")
}),
space: ({ theme }) => ({
...theme("spacing")
})
},
plugins: []
} satisfies Config;In your tailwind.css add this to enable default headlines:
@layer base {
h1 {
@apply text-head-xl font-head;
}
h2 {
@apply text-head-lg font-head;
}
h3 {
@apply text-head-md font-head;
}
h4 {
@apply text-head-sm font-head;
}
h5 {
@apply text-head-xs font-head;
}
h6 {
@apply text-head-2xs font-head;
}
}<div class="grid gap-fix-sm p-res-md"></div>If you want to optimize the size of the loaded styles, you might skip loading @db-ui/foundations/build/css/db-ui-foundations.css.But there are some required styles for this Design-System to work properly.
/* The theme contains all prop required for components like spacings, colors, ... */
@import "@db-ui/foundations/build/css/default-theme.css";
/* The font include uses default font families based on your bundling paths (relative, absolute, webpack, rollup) */
@import "@db-ui/foundations/build/css/fonts/include.css";
/* The required styles will normalize css and add focus and default font to body */
@import "@db-ui/foundations/build/css/init/required.css";
/* The default root adds a default color space (neutral) and a density (regular) */
@import "@db-ui/foundations/build/css/init/default-root.css";We provide a CLI tool to auto migrate your source code.
