Introduction Table of Contents Setup 1. Install Tailwind https://tailwindcss.com/docs/installation 2. Import the Porsche Design System Tailwind Theme Below the @import "tailwindcss"; line in your global css file, import the Porsche Design System Tailwind theme:
@import 'tailwindcss'; @import '@porsche-design-system/components-{js|angular|react|vue}/tailwindcss';
Theme Configure a Theme switch By default, the color tokens use the light theme. To enable the dark or auto (automatic dark mode based on system settings) theme, you need to add the corresponding class .dark or .auto to the <html> element. This change will apply the selected theme to all child elements. To implement a three-way theme toggle (light, dark, auto), dynamically update the <html> element’s class using JavaScript:
document.documentElement.classList.remove('light', 'dark', 'auto'); document.documentElement.classList.add(theme); // theme is the selected theme here ('light', 'dark' or 'auto')
Using the Tailwind Theme To apply a fixed color, you can use any color token with a -light or -dark suffix. Examples: .bg-surface — Automatically adapts to the closest .light, .dark, or .auto class on a parent HTML element. .bg-surface-light — Forces the light theme color. .bg-surface-dark — Forces the dark theme color.

It's also possible to use auto, which applies light or dark theme depending on the operating system settings automatically.LightDarkAuto (sync with operating system)DirectionThe dir global attribute in HTML changes the direction of text and other content within an element. It's most often used on the <html> tag to set the entire page's direction, which is crucial for supporting languages that are written from right to left (RTL), such as Arabic and Hebrew. For example, using <html dir="rtl"> makes the entire page display from right to left, adjusting the layout and text flow accordingly.LTR (left-to-right)RTL (right-to-left)Text ZoomTo ensure accessibility and comply with WCAG 2.2 AA standards, it is mandatory for web content to support text resizing up to at least 200% without loss of content or functionality. Using relative units like rem is a best practice for achieving this, as they allow the text to scale uniformly based on the user's browser settings.100%130%150%200%
