Global Theme#

All system colors are controlled via the CSS color-scheme property and are included in our mandatory Global Styles. These styles also provide utility classes for selecting the active theme and a polyfill to ensure compatibility with browsers that do not yet support light-dark() (see browser support).

By default, color tokens use the light theme. To enable the dark theme or automatic theme switching based on system settings, add the .scheme-light, .scheme-dark or .scheme-light-dark CSS class to the <html> element or any HTML element. This applies the selected theme to all child elements.

Learn more in the Theme section.

Prefixing#

In case of a micro-service architecture, multiple instances and versions of the Porsche Design System can be combined in a final application. This could cause conflicts due to the way how custom webcomponents are registered in the browser. During the bootstrap phase of the Porsche Design System, custom elements are defined. If a second application wants to register Porsche Design System again it will cause issues especially when different versions are used.

A way of preventing those conflicts is by using a unique custom prefix for the components. Simply pass your desired prefix to the prefix property of PorscheDesignSystemProvider.

// index.tsx

import ReactDOM from 'react-dom';
import { PorscheDesignSystemProvider } from '@porsche-design-system/components-react';
import { App } from './App';

ReactDOM.render(
  <React.StrictMode>
    <PorscheDesignSystemProvider prefix="sample-prefix">
      <App />
    </PorscheDesignSystemProvider>
  </React.StrictMode>,
  document.getElementById('root')
);

In the following example the PHeading component will render as <sample-prefix-p-heading>.

// App.tsx

import { PHeading } from '@porsche-design-system/components-react';

export const App = (): JSX.Element => <PHeading>Some heading</PHeading>;
