A library containing all tokens of DB UX Design System (technical components).

We currently support:

• CSS
• SCSS
• Tailwind

npm i @db-ui/foundations

The defaults for db-ui-foundations.css are:

• Tonality: regular
• Adaptive Coloring: neutral-0

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.

// main.ts / main.js
import "@db-ui/foundations/build/css/db-ui-foundations.css";
// optional: to use classes like e.g. db-ui-bg-success
import "@db-ui/foundations/build/css/color-classes.css";

.my-container {
	padding: var(--db-spacing-fixed-md);
}

<div class="db-ui-regular db-ui-bg-success my-container"></div>

Based on your technology/setup you need to change the paths of the assets folder:

• Default: points to ../assets
• Webpack: points to ~@db-ui/foundations/assets
• Rollup: points to @db-ui/foundations/assets

// index.scss
@use "@db-ui/foundations/build/scss/rollup.assets-paths" as *;
@use "@db-ui/foundations/build/scss/icon/icons" as *;
@use "@db-ui/foundations/build/scss/db-ui-foundations" as *;
// optional: to use db-ui-bg-success
@import "@db-ui/foundations/build/scss/color-classes" as *;
// optional: to use use $db-spacing-fixed-md
@use "@db-ui/foundations/build/scss/variables.global" as *;

.my-container {
	padding: $db-spacing-fixed-md;
}

<div class="db-ui-regular db-ui-bg-success my-container"></div>

//tailwind.config.cjs

const tokens = require("@db-ui/foundations/build/tailwind/tailwind-tokens.json");

module.exports = {
	content: ["./index.html", "./src/**/*.{js,jsx,ts,tsx}"],
	plugins: [],
	theme: {
		screens: tokens.screens,
		spacing: tokens.spacing,
		boxShadow: tokens.elevation,
		gap: ({ theme }) => ({
			...theme("spacing")
		}),
		space: ({ theme }) => ({
			...theme("spacing")
		})
	}
};

<div class="p-fix-md"></div>

We use icon fonts as woff2 files for all our icons. We auto generate these files out of .svg files.

If you have custom icons and want to use them for foundations and/or in components, you need to generate a woff2 file.

For this run:

node node_modules/@db-ui/foundations/scripts/generate-icon-fonts/index.js --src ./my-path-to/icons --fontName my-name

We search for all **/*.svg files inside the src directory and create a new icon font with the provided name.

NOTE: We use 3 different sizes for components (16,20,24) to show more or less details. You can do the same by providing another file with a size postfix for example "icon_file_name_16.svg".

In your app you need to include some of the generated files:

./my-path-to/icons/fonts/my-name.woff2

./my-path-to/icons/fonts/font-face.css

Now you can use your icons with your font-family: my-name, e.g.:

<!--example.html-->
<i class="my-name">icon_file_name</i>

If you like to use a custom icon in one of our components you can do it by overwriting the default font-family like this:

<!--example.html-->

<p class="icon-family-my-name" data-icon="icon_file_name">Test</p>
<!-- or -->
<p data-icon-family="my-name" data-icon="icon_file_name">Test</p>

If you update a svg inside assets/icons/functional/images you need to recreate the woff2 file.

For this you just need to run

npm run generate:icon-fonts

Your new icon should be inside assets/icons/functional/fonts/info.json and you should see it inside assets/icons/functional/fonts/index.html in the browser.
